but with an added -Xmx1124m and it works.
I don't know how to reproduce the same while running the decompile.bat file as the file just runs another python file.
I am using MCP 9.18 and trying to decompile Minecraft 1.8.8. My computer has 2GB of memory with 1.9GB being usable.
ANSWER
Answered 2021-Dec-06 at 05:49Go to conf/mcp.cfg. Find this line
CmdFernflower = %s -jar %s -din=1 -rbr=0 -dgs=1 -asc=1 -log=WARN {indir} {outdir}
and change it to this
CmdFernflower = %s -Xmx1.7G -jar %s -din=1 -rbr=0 -dgs=1 -asc=1 -log=WARN {indir} {outdir}
That should give MCP 1.7gb of ram when decompiling. I really recommend to get more ram even 8gb will be a huge help

you can see that the json file above have the "path".what the batch file did is output all of the value of "path" into a text file called "path.txt".The code above work fine on 1.7.10.json file,but it never output anything when i try to use it with 1.8.8.json.

from my look,There is the "url" value that store link to download these libaries. My guess is that we can use the url links to create path:Example:
https://libraries.minecraft.net/net/java/dev/jna/platform/3.4.0/platform-3.4.0.jar
We can reuse that link and turn it into a path,by deleting "https://libraries.minecraft.net/"
https://libraries.minecraft.net/ net/java/dev/jna/platform/3.4.0/platform-3.4.0.jar (delete the blue bold one.)
So,how are we gonna erase that bold blue text,and only save the path into a txt file like path.txt using batch? (Sorry if my english is bad,english is not my main speaking thing.You can edit the if i write something wrong.)
ANSWER
Answered 2021-Nov-15 at 12:27Remember that batch and cmd is not suitable to parse JSON file !
But if you insist to use a batch file just give a try with this ugly code :
@echo off
Set "PathLink=%~dp0PathLink.txt"
If Exist "%PathLink%" Del "%PathLink%"
SetLocal EnableDelayedExpansion
@for /f "tokens=1-3 delims=:{}, " %%A in (1.8.8.json) do (
If /I %%~A==url (
Set "link=%%~C"
Set link=!link:"=!
Set link=!link://libraries.minecraft.net/=!
Set link=!link://launchermeta.mojang.com/=!
Set link=!link://launcher.mojang.com/=!
echo !link!>>"%PathLink%"
)
)
Start "" /MAX "%PathLink%"
EXIT
As a result you can get :

QUESTION
Static final variable initialization (in Java) incorrect during Kotlin CI Tests
Asked 2021-Jul-19 at 16:16
I manage an open source project and have a user reporting a situation which I think is impossible according to Java's order of initialization of static variables in classes. The value of a static final class variable is incorrect, apparently resulting from different results of a dependency's static method based on its own static final variable.
I'd like to understand what's happening in order to figure the best workaround. At the moment, I am baffled.
The problemThe main entry point for my project is the class SystemInfo which has the following constructor:
public SystemInfo() {
if (getCurrentPlatform().equals(PlatformEnum.UNKNOWN)) {
throw new UnsupportedOperationException(NOT_SUPPORTED + Platform.getOSType());
}
}
When run by itself, the problem doesn't reproduce; but when run as part of many tests being executed a larger build (mvn install) it is consistently reproducible, implying the problem is likely associated with multithreading or multiple forks. (To clarify: I mean the simultaneous initialization of static members in two different classes, and the various JVM-internal locking/synchronization mechanisms associated with this process.)
They receive the following result:
java.lang.UnsupportedOperationException: Operating system not supported: JNA Platform type 2
This exception implies two things are true when SystemInfo instantiation begins:
- The result of
getCurrentPlatform()is the enum valuePlatformEnum.UNKNOWN - The result of
Platform.getOSType()is 2
However, this situation should be impossible; a value of 2 would return WINDOWS, and unknown would return a value other than 2. Since both variables are both static and final they should never simultaneously reach this state.
I have tried to reproduce this on my own and failed, and am relying on a report from a user executing tests in their Kotlin-based (kotest) framework.
The user's MCRE simply invokes this constructor as part of a larger number of tests, running on the Windows operating system:
public class StorageOnSystemJava {
public StorageOnSystemJava(SystemInfo info) {
}
}
class StorageOnSystemJavaTest {
@Test
void run() {
new StorageOnSystemJava(new SystemInfo());
}
}
Underlying code
The getCurrentPlatform() method simply returns the value of this static final variable.
public static PlatformEnum getCurrentPlatform() {
return currentPlatform;
}
This is a static final variable populated as the very first line in the class (so it should be the first thing initialized):
private static final PlatformEnum currentPlatform = queryCurrentPlatform();
where
private static PlatformEnum queryCurrentPlatform() {
if (Platform.isWindows()) {
return WINDOWS;
} else if (Platform.isLinux()) {
// other Platform.is*() checks here
} else {
return UNKNOWN; // The exception message shows the code reaches this point
}
}
This means that during class initialization, all of the Platform.is*() checks returned false.
However, as indicated above this should not have happened. These are calls to JNA's Platform class static methods. The first check, which should have returned true (and does, if called in the constructor or anywhere in code after instantiation) is:
public static final boolean isWindows() {
return osType == WINDOWS || osType == WINDOWSCE;
}
Where osType is a static final variable defined thus:
public static final int WINDOWS = 2;
private static final int osType;
static {
String osName = System.getProperty("os.name");
if (osName.startsWith("Linux")) {
// other code
}
else if (osName.startsWith("Windows")) {
osType = WINDOWS; // This is the value being assigned, showing the "2" in the exception
}
// other code
}
From my understanding of the order of initialization, Platform.isWindows() should always return true (on a Windows OS). I do not understand how it could possibly return false when called from my own code's static variable initialization. I've tried both the static method, and a static initialization block immediately following the variable declaration.
- User calls the
SystemInfoconstructor SystemInfoclass initialization begins ("T is a class and an instance of T is created.")- The
static final currentPlatformvariable is encountered by the initializer (first line of class) - The initializer calls the static method
queryCurrentPlatform()to obtain a result (same result if the value is assigned in a static block immediately following the static variable declaration) - The
Platform.isWindows()static method is called - The
Platformclass is initialized ("T is a class and a static method of T is invoked.") - The
Platformclass sets theosTypevalue to 2 as part of initialization - When
Platforminitialization is complete, the static methodisWindows()returnstrue - The
queryCurrentPlatform()sees thetrueresult and sets thecurrentPlatformvariable value (This is not happening as expected!) - After
SystemInfoclass initialization is complete, its constructor executes, showing the conflicting values and throwing the exception.
Some workarounds stop the problem, but I don't understand why they do:
Performing the
Platform.isWindows()check anytime during the instantiation process (including the constructor) properly returnstrueand assigns the enum appropriately.- This includes lazy instantiation of the
currentPlatformvariable (removing thefinalkeyword), or ignoring the enum and directly calling JNA'sPlatformclass.
- This includes lazy instantiation of the
Moving the first call to the
staticmethodgetCurrentPlatform()out of the constructor.
These workarounds imply a possible root cause is associated with executing static methods of multiple classes during class initialization. Specifically:
- During initialization, the
Platform.isWindows()check apparently returnsfalsebecause code reaches theelseblock - After initialization (during instantiation), the
Platform.isWindows()check returnstrue. (Since it is based on astatic finalvalue it should not ever return different results.)
I've thoroughly reviewed multiple tutorials about Java clearly showing the initialization order, as well as these other SO questions and the linked Java Language Specs:
ANSWER
Answered 2021-Jul-17 at 00:49DISCLAIMER: I'm writing this as an answer because I don't know how to make it fit into a comment. If it doesn't help you let me know, and I'll delete it.
Let's start with a small recap which given the question quality, I'm sure you're aware of already:
- A field which is
staticto a class, means that it only exists once for any instance. No matter how many instances of the class you create, the field will always point to the same memory address. - A field which is
finalmeans that once initialized, its value cannot change any longer.
So, when you mix these two into a static final field, it means:
- You only have one value for that field, no matter how many instances
- Once the value is assigned, it doesn't change any longer
So, my suspect is not that there is any thread-safety issue (I don't think you're running your tests in parallel, so I guess no two-threads would simultaneously work on these objects, right?), but rather that a previous test of your test suite has initialized the variables differently and, being they run into the same JVM, they don't change any longer their values.
Take this very simple test example.
I have one very basic class:
public final class SomeClass {
private static final boolean FILE_EXISTS;
static {
FILE_EXISTS = new File("test").exists();
}
public SomeClass() {
System.out.println("File exists? " + FILE_EXISTS);
}
}
The above class simply has a static final boolean saying whether a certain file named test exists into the working directory. As you can see, the field is initialized once (final) and will be the same for each instance.
Now, let's run these two very simple tests:
@Test
public void test_some_class() throws IOException {
System.out.println("Running test_some_class");
File testFile = new File("test");
if (testFile.exists()) {
System.out.println("Deleting file: " + testFile.delete());
} else {
System.out.println("Could create the file test: " + testFile.createNewFile());
}
SomeClass instance1 = new SomeClass();
}
@Test
public void other_test_some_class() {
System.out.println("Running other_test_some_class");
SomeClass instance2 = new SomeClass();
}
In the first test, I check if file test exists. If it does exists, I'll delete it. Else, I'll create it. Then, I'll initialize a new SomeClass().
In the second test, I simply initialize a new SomeClass().
This is the output of my tests run together:
Running other_test_some_class //<-- JUnit picks the second test to start
File exists? false //<-- The constructor of SomeClass() prints the static final variable: file doesn't exist
Running test_some_class //<-- JUnit continues running the first test
Could create the file test: true //<-- it is able to create the file
File exists? false //<-- yet, the initializer of new SomeClass() still prints false
The reason why it prints false, even though we clearly created the test file before initializing new SomeClass(), is that the field FILE_EXISTS is static (hence shared across all instances) and final (hence initialized once, lasting forever).
So if you wonder why private static final int osType; has a value which returns you UNKNOWN when you run mvn install but not when you run the single test, I'd simply look what test, in your full test suite, has already initialized it with a value that you don't expect.
There are two types of solution for this, and they depend on your production code.
It may be that, functionally, you actually need this field to be maybe final to the instance of the class, but not static. If that's the case, you should just declare it final to the class (once initialized, it doesn't change, but still you have one different value per instance).
Or, it may be that you really need the field to be static final in production, but not during tests as you initialize a new test context each time. If that's the case, you should configure your test plugin to reuseForks = false (meaning a fresh JVM fork is created for each test class, and that guarantees you that each test class will start with a fresh memory for your static final fields):

ANSWER
Answered 2021-Jun-22 at 07:45You must add annotation for the "whole" application (which @Push is) to your central configuration place (which is the class implementing AppShellConfigurator). As the error states:
Found app shell configuration annotations in non `AppShellConfigurator` classes.
Please create a custom class implementing `AppShellConfigurator` and move the following annotations to it:
- @Push from net.cbsolution.chameleon.ui.views.AlertView
Remove @Push from net.cbsolution.chameleon.ui.views.AlertView (as it's already set on your MyAppShellConfigurator as seen in your code paste).
QUESTION
Assign .on('click') in a for loop to each array element individually
Asked 2021-May-28 at 11:12
Is there a possibility to toggleText() for each element of the array separately?
Right now, when clicked, the values are changed for every single element at the same time and I'd like to go over them one by one as they're clicked.
$(function() {
var jap = ["kau", "matsu", "shiru"];
var eng = ["to buy", "to wait", "to know"];
var tds = [$('#td1'), $('#td2'), $('#td3')]
for (i = 0; i < tds.length; i++) {
$(tds[i]).on('click', function(){
for(i = 0; i < tds.length; i++) {
$(tds[i]).toggleText(jap[i], eng[i]);
}
});
}
});
Ideally, I'd like to change the text inside a table cell on each individual click for each array element.

Here's the HTML with the table:

Here's additional meaning of the words I'd like to display:

I also added ids to the tds that are supposed to show the meaning like this for each individual td:
kau
kai-
taberu
// and so on
and changed the js code to this:
const $tds = $("#tb td[id]");
$("#tb").on("click", "td[id]", function() { ... }
However, as I mentioned in the comment, that one fragment changes the structure of the table and makes tds appear in wrong places. This fragment specifically:
$tds.each(function(i) {
$(this).text(jpArr[i])
$(this).data("lang","ja")
})
If removed, the code works but the cells require two clicks to show the meaning.

QUESTION
Java Obfuscation - with proguard
Asked 2021-May-22 at 05:51
I'm using oshi for creating a unique key in my application. I have created a fat jar with maven shaded plugin from the project. The fat jar is working fine without obfuscation. But if I obfuscate the jar using ProGuard, the jar is throwing the following error while trying to run.
Exception in thread "main" java.lang.UnsatisfiedLinkError: com.sun.a.H.h()Ljava/lang/String;

So I have created a proguard.confile to manage obfuscation rules.
-keep public class com.acme.qpguard.editor.Application { *; }
-keep class org.apache.log4j.** { *; }
-keep class oshi.hardware.** { *; }
-keep class oshi.util.** { *; }
-keep class oshi.software.** { *; }
-keep class oshi.SystemInfo { *; }
But this is not helping me. The jar is still throwing java.lang.UnsatisfiedLinkError, caused by oshi. Looking forward for pointers to solve this issue. Thanks in advance.

np.where() returns MemoryError
Asked 2021-Mar-20 at 12:48
The number of np.where()'s I would assume is the issue since removing 1 will allow the function to work. I'm not aware of another way to edit a name other than an if else. I figured this would be faster. Mapping comes to mind as well, but I'm not sure how to return the names that are not changed. Any help understanding the best practice for this desired outcome would be very much appreciated!

ANSWER
Answered 2021-Mar-20 at 12:48When you are dealing with more than two choices, use np.select.
conditions = [df['name'] == 'A J Greer', df['name'] == 'Alexis Lafrenière', ...]
choices = ['A.J. Greer', 'Alexis Lafreniere', ...]
df.select(conditions, choices, default = df.name)
You can also use dictionary as a lookup table
name_table = {
'A J Greer': 'A.J. Greer',
'Alexis Lafrenière': 'Alexis Lafreniere',
'B J Crombeen': 'B.J. Crombeen',
# and so on
}
df['name'].str.title().apply(lambda x: name_table.get(x, x))
# or
def player_name_filter(dataf , column_name):
dataf[column_name] = dataf[column_name].str.title().map(name_table)
return dataf
df = df.pipe(player_name_filter, column_name='name')
# problem NaN for players not in the tables
QUESTION
JaCoCo Injection Error executing maven test via ssh
Asked 2020-Dec-12 at 07:09
I am attempting to set up continuous integration testing for my open source project on a remote AIX server. I can execute tests just fine in an interactive shell:
$ ssh gate.polarhome.com -p 775 -l oshi
$ echo $PATH
> /usr/java8_64/bin:~/apache-maven-3.6.3/bin/:/opt/freeware/bin:/usr/local/bin:/usr/bin:/etc:/usr/sbin:/usr/ucb:$HOME/bin:/usr/bin/X11:/sbin:.
$ cd ~/git/oshi
$ mvn test -B
When executing in this interactive environment using exactly these steps, the test executes properly. However, when attempting to execute the identical commands via an SSH command line, the JaCoCo plugin fails:
$ ssh gate.polarhome.com -p 775 -l oshi "export PATH=/usr/java8_64/bin:~/apache-maven-3.6.3/bin/:/opt/freeware/bin:/usr/local/bin:/usr/bin:/etc:/usr/sbin:/usr/ucb:$HOME/bin:/usr/bin/X11:/sbin:.; cd ~/git/oshi; mvn test -B"
After entering password, the commands proceed through the mvn test but then fail with an exception:

Using the -X switch on maven, the log line immediately preceding the error is:
[DEBUG] Configuring mojo org.jacoco:jacoco-maven-plugin:0.8.6:prepare-agent from plugin realm ClassRealm[plugin>org.jacoco:jacoco
I have searched StackOverflow for similar issues. The closest I found was this question with similar symptoms, but associated with a Jenkins versioning problem.
I've tried various other attempts at solutions:
- Deleted the
.m2/repositoryand let it rebuild - Added
cleanto the maven commands - Attempted to skip JaCoCo using
jacoco.skip=true
I'm pretty sure the issue has to do with the "injection" involved with JaCoCo, but can't figure out how to bypass, skip, or further investigate problems with this.
I'm at a loss for a next troubleshooting step. What is different about an interactive ssh enviornment vs. ssh command-line that would cause different behavior from the jacoco-maven-plugin?
ANSWER
Answered 2020-Dec-12 at 07:09It turns out that there was one setting in my interactive .profile that was key to resolving this:
ulimit -n 8192
Seems rather than trying to copy path and other things over, just using source .profile would have saved me a lot of troubleshooting time.
QUESTION
Use an image as a mask for another image
Asked 2020-Dec-06 at 15:48
I'm making a website that I wanted to be a white page that you could stamp to make another image appear under. So when you click, you make a holepunch. Like this exemple :
So I managed to have a randomized image in the background as I click which is fine for what I want, and to be able to .append() the holepunches. But I don't know how to do the mask thing I've been digging online for a few things and help, and managed to make it work in certain cases but not that one...
It should be like that (I guess) :
- image in the background
- white shape in front
- the star shape is making a holepunch in the white shape
For now, the only thing I managed to do is to have the picture besides a bigger holepunch (which is my original img) but when I click it doesn't make any holepunch, it justs add the stamp.
Here is the code :
var images = ["https://icatcare.org/app/uploads/2018/07/Thinking-of-getting-a-cat.png", "https://ichef.bbci.co.uk/news/1024/cpsprodpb/151AB/production/_111434468_gettyimages-1143489763.jpg"];
$(document.body).click(function(c) {
var tw = 100 / 2;
var th = 30 / 2;
var x = Math.floor((Math.random() * images.length));
document.getElementById('random').src = images[x];
$("#random").css({
position: 'absolute',
display: "block",
left: 0,
top: 0
});
var tw = 50 / 2;
var th = tw;
$('#holepunch:last').clone().appendTo(this).css({
position: 'absolute',
display: "block",
left: c.pageX - tw - $(this).position().left,
top: c.pageY - th + $(this).scrollTop()
});
});
body{
background: lightgrey;
width: 100vw;
height: 100vh;
z-index: 1;
opacity: 1;
}
.fauxbody{
z-index: 100;
position: fixed;
width: 100vw;
height: 100vh;
background-color: white;
top: 0;
left: 0;
-webkit-mask:
-moz-element(#holepunch) 1vw 1vh no-repeat,
linear-gradient(#fff 0 0);
mask-composite:exclude;
}
#random{
z-index: -100;
width: 100vw;
height: auto;
}
#holepunch{
width: 50px;
height: auto;
}

Install oshi
You can download it from GitHub, Maven.
You can use oshi like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the oshi component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
