QUESTION
ANSWER
Answered 2021-Apr-30 at 14:33You need update "Debugger for Java" extension to 0.33.1, which has fixed it.
See https://github.com/microsoft/vscode-java-debug/issues/995
Update: "Debugger for Java" 0.33.1 also requires your VS Code version to be 1.55.0 and above.
QUESTION
So Java's debug interface is using JVMTI as a backend....but JVMTI needs to be compiled on the target architecture, so are these JVMTI functions which are used by JDI pre-compiled and shipped with the JDK as libraries? This would mean that I can use those pre-compiled libraries without using JDI...is that right? I am assume only a handful of functions are already compiled but if I need exactly those functions then I don't need to go through the hassle of compiling them myself....

Is it possible to use a Java agent to get the number of instances of any Java class? For example if we have
...ANSWER
Answered 2021-Apr-30 at 11:13In order to count instances, you'll need to walk through the entire heap. Java Agents don't have such functionality. Basically, all they have is Instrumentation API.
The task is simple to do with JVM TI. There is IterateOverInstancesOfClass function which does almost what you want. JVM TI is not cross-platform, but you may create a JAR with dynamic libraries for the main supported platforms, and load the suitable one in runtime. That's how JNA works, for example.
The closest pure Java alternative is HotSpot diagnostic command to get a class histogram:

Here I have created a JTable
and surround it with JScrollPane
. I have created an update and refresh button so that I can refresh and update the values in the data set. But the problem is with the refresh button whenever I click the button it appears the data more than one time. Like I have 10 data set after updating the name when I refresh the button it is showing again 10 data means a total of 10+10=20 same types of data.

QUESTION
In the class I am testing, I want to mock the whole DataAccess class that is used as a member variable. The DataAccess class is just abstracting the SQLite database connection.
I have created a replacement MockDataAccess class that connects to a test database, but the main database still seems to be called - what am I doing wrong?
Edit: have updated where I am patching as recommended and originally did, but still isn't working?

...ANSWER
Answered 2021-Mar-29 at 18:14I found that my problem was that it wasn't patching data_access, because data_access had already been declared when I created my test instance using a pytest fixture.
Also, I found that new_callable wasn't in fact behaving as I thought it would, so I have used return_value instead and passed an instance of MockDataAccess. Now my test database is being called as expected.
New test_query.py (only bits changed):
QUESTION
I have a small application with an endpoint which calls some converter library. My Run Configuration
is of type Tomcat
and deploys an exploded war which is my application.
In the pom.xml
's of that application, I have an external library I need to debug. That library is called within my application, obviously.
When I launch the Tomcat Run Configuration
in Debug
mode, the logs indicate that the Agent seems to have been set up properly and the artefact is deployed successfully (the following is a subset of the logs which I thought were relevant):
ANSWER
Answered 2021-Feb-10 at 20:48Turns out there was a misunderstanding. I thought the Test class was making a network call to the localhost
Tomcat instance, when in fact it called the source code directly.
That's why when I was launching the Tomcat Run Configuration in Debug mode I would get a registered breakpoint in my source code, but it would never suspend the application, despite me seeing the logs.
And since the application was configured to output logs in a file in target
, I thought the logs were coming from Tomcat.
Stepping in from the Test class launched in Debug mode brought me to the application code, and eventually also reached the library code. That is also why I was seeing logs coming from the library, but without seeing the registered breakpoint when I was running the Test class normally after launching the Tomcat Run Configuration in Debug mode.
Ugh. That was an embarrassing and time-consuming journey.
QUESTION
I am trying to use aws Transcribe to convert a wav file to text. I have uploaded a wav file to S3, which is located here and it has public read/write permissions: https://s3.us-east-1.amazonaws.com/csld8xmsdksdf8s9sk3mmdjsdifkjksdijsldk/Transcribe2.wav. The wav file is valid. I can download it in my browser and replay it (and it sounds like the origin recording), so I think we can rule out an invalid input file, file permissions, etc.
I am using java version: 1.8.0_275 for mac.
I expect my program to give me back the transcribed text: "Hello amazon Subscribe, what is this?"
Here is the actual program output, including exception:
