Unable to debug Java Card Applet Code using Java Card Simulator.

I am trying to debug a Java Card Project in VS Code, but the breakpoints are not hit.

Environment

• Operating System: Windows 10.
• JDK version: 17.0.5 LTS
• Visual Studio Code version: 1.74.2
• Java extension version:
• Java Debugger extension version: 0.47.2022112823

Steps To Reproduce

1. Download and Install Java Card Simulator from Oracle. [Java Card Classic Development Kit 3.0.5u4]
   • https://www.oracle.com/java/technologies/java-archive-downloads-javame-downloads.html#javacardkitv305
2. Download and Extract Sample Java Card Project. [Sample.zip attached.]
3. Terminal 1: Start the Simulator.
   • cd "{Your_Install_Location}\Java Card Development Kit 3.0.5u4\bin}"
   • cref_tdual.exe -p 9025 -debugPort 7019
4. Terminal 2: Launch APDU Tool.
   • cd "{Your_Install_Location}\Java Card Development Kit 3.0.5u4\bin}"
   • apdutool.bat -p 9025
5. Load the cap file in Simulator.
   • Copy paste the contents of {Your_Extract_Location}/apdu_scripts/cap-com.sample.script in Terminal-2 and press Enter
6. Installing the application in Simulator.
   • Copy paste the contents of {Your_Extract_Location}/apdu_scripts/create-com.sample.MyApplet.script in Terminal-2 and press Enter.
7. Terminal 3: Launch Debug Proxy.
   • cd "{Your_Install_Location}\Java Card Development Kit 3.0.5u4\lib"
   • java -jar jc-debug-proxy.jar -port 8989 -vmPort 7019 -capPath {Your_Extract_Location}\Sample\deliverables\com\sample\javacard\sample.cap

---- Debugging In VS Code [Doesn't work]-----

1. Open the Sample project in VS Code.
2. Start the debug session in VS Code.(Press F5). [A launch.json with correct configurations is already present.]
3. Open the file src/com/sample/MyApplet.java and set a breakpoint at line 57.
4. In Terminal-2
   • 0x00 0xA4 0x04 0x00 0x06 0x89 0x89 0x89 0x89 0x89 0x81 0x7F;
   • Press Enter.
   • The breakpoint at Line-57 should be hit. [This doesn't work.]

---- Debugging with Eclipse for Java [Working] ----------

1. Open the Sample project in Eclipse.
2. Select File -> Open Projects From File System -> Select the Sample Directory.
3. Setup Debug Configuration.
   • Select Run -> Debug Configurations...
   • On Left Panel Select Remote Java Application.
   • In Project Field, Click on Browse and Select Sample.
   • Change the port to 8989
   • Click on Apply then Debug.
4. Open the file src/com/sample/MyApplet.java and set a breakpoint at line 57.
5. In Terminal-2
   • 0x00 0xA4 0x04 0x00 0x06 0x89 0x89 0x89 0x89 0x89 0x81 0x7F;
   • Press Enter.
   • The breakpoint at Line-57 should be hit. [Working]

Additional Informations

Sample.zip

まず、Java Card Simulator、Debug Proxy、APDU Tool、および提供された Sample プロジェクトを使ってブレークポイントの失敗を再現し、VS Code F5 セッションと、ポート 8989 で動作している Eclipse のリモートデバッグセッションを比較します。既存の launch.json と src/com/sample/MyApplet.java:57 のブレークポイントを調査します。完了条件は、VS Code で APDU コマンドがそのブレークポイントで一貫して停止することです。
