When you run the code shown below, you're getting calling a method that returns a new instance of SimpleDateFormat that uses the default constructor instead of the constructor defining the format you require ("dd-MMM-yyyy").

QUESTION

Cipher.getInstance() slow when called from multiple JVM instances on unix platforms

Asked 2020-May-05 at 11:13

I have an application that spawns multiple short-lived java (IBM Java 8) programs in which they need to make an SSL request to a server. I am running into an issue where if I run several instances of these in parallel they all take an equal amount, and much longer time to run. In some cases it saves almost no time as if I had run them serially. For example, if 1 instance takes 3 seconds to run, if I run 5 in parallel they might all take 15 seconds to run.

I have noticed that this does not seem to be an issue on Windows systems. I'm not very familiar with the Java security libraries, and I did find this post Slow SecureRandom initialization which seems like it might be the root cause, but I was unable to get the code snippets to work for the Cipher.getInstance() call.

To demonstrate the problem, I have distilled it down to this code snippet:

IBMJCEPlusFIPS is a U.S. export-controlled provider. Due to this, IBM JCE verifies the signatures of all bundled security JARs, in an attempt to enforce this.

If you take a few stacktrace samples of the main thread, you will see that it is indeed mainly busy verifying JAR files and a self-test (omitted here).

How to preserve comments in Eclipse JDT

Asked 2019-Sep-17 at 20:33

I'm using Eclipse JDT to modify java source code. This happens in three steps:

At first I create an instance of org.eclipse.jdt.core.dom.CompilationUnit and call it's accept() method with an ASTVisitor
Then I manipulate the CompilationUnit. I remove and add ASTNodes to the tree (this is not shown here)
Then I write compilationUnit.toString() back to a file.

Creation of the compilation unit:

ANSWER

Answered 2019-Sep-17 at 20:33

I believe you start losing information when you do compilationUnit.toString(). Later when you format the text, you finally lose any existing formatting.

Instead, I recommend to learn how to use ASTRewrite, which allows you to incrementally apply your changes into the existing AST. The goal is to let the rewrite generate the minimal TextEdits that can be applied to the (original!) document.

If using ASTRewrite inside your visitor is not an option, you could even try using ASTRewrite in "recording" mode, see org.eclipse.jdt.core.dom.CompilationUnit.recordModifications().

ANSWER

Answered 2018-Mar-21 at 05:42

Very odd, given that the class that can't be found is in the same jar as the BuildPathManager class which is calling a method in the problem class. This implies some corruption somewhere. First of all, take a look at the org.eclipse.m2e.jdt_1.7.0.me201611191457.jar, which will be in the plugins folder of the MyEclipse installation. You can look at the jar with any archive program (e.g. winzip or winrar); check the org/eclipse/m2e/jdt/internal folder within the jar file, it should contain the class that wasn't found. If it isn't there, then I suggest a re-install of the latest release of MyEclipse. If it is there, there might be some caching problem, so start MyEclipse with the -clean option from the command line to see if that helps (in a terminal/command window go to the installation folder and enter the command myeclipse -clean).

If you try the latter option but still have no success, try a fresh workspace and/or reinstall MyEclipse anyway.

You have used a correct way to make the test resources available, by configuring the test SourceSets "resources" directory.

But there are two small errors in your exclusion rules:

you need to add test directory in the excluded directories list
you forgot about the ending '/' character ( write 'src/' instead of 'src')

Eclipse Oxygen + Java 9

In order to test if a project is ready for java 9, I tried the last couple hours to get eclipse compiling the complete project.
Here's what I did:

I'm using XUbuntu in a virtual machine by the way...

I installed the latest openjdk-9-* packages and removed all java 8 packages.

I downloaded the eclipse installer for eclipse oxygen and installed the default version of eclipse for Java SE.

I started eclipse and installed the Java 9 Support Package from the marketplace and tried importing the gradle project.

Everything went more or less fine until this point. (Had a couple problems with the packages and eclipse threw some error messages but all in all it worked.)

The project was successfully imported,but I get this error messages:
