Debugger opens *.class file despite there being an overridden *.java file in the project's src folder

[marecabo]

When debugging a project where I have put copies of Java files from a dependency in my project's src folder (but in another module) to adjust its behavior, and placing break points in these overwritten Java files, the debugger always opens the *.class file of the dependency, which does not contain my changes.

Example project which works: https://github.com/marecabo/java-debug-demo/tree/works
Example project where this issue occurs: https://github.com/marecabo/java-debug-demo/tree/does-not-work

Environment

• Operating System: RHEL 8.9
• JDK version: openjdk 21.0.2 2024-01-16 LTS
• Visual Studio Code version: 1.88.1
• Java extension version: v1.29.0
• Java Debugger extension version: v0.57.0

Steps To Reproduce

1. Checkout example project: git clone -b does-not-work https://github.com/marecabo/java-debug-demo.git
2. Place a breakpoint in other/src/main/java/tech/tablesaw/table/Relation.java:261.
   This file overrides a file from a dependency and changes its behavior, see marecabo/java-debug-demo@40bb99b
   
3. Debug run/src/main/java/com/project/my/run/Main.java

Current Result

language-support-for-java.log

Relation.class is opened which obviously does not show the changes I made in Relation.java. The execution marker (yellow highligted line) is - however - at the line number of the original breakpoint in other/src/main/java/tech/tablesaw/table/Relation.java:261, even if that line in Relation.class only contains } or is even empty.

Expected Result

other/src/main/java/tech/tablesaw/table/Relation.java is opened with my changes.

Additional Informations

So far I found out, that this issue only occurs, when the overridden Java file is not located in the same maven module, where the main class which is debugged resides. As a workaround, moving the overridden Relation.java file to the run module is enough to make it work as expected.

Thanks for your work at this extension.
