Hi mozhuanzuojing, I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

Suggestions

• Run Java: Clean Java language server workspace from the VS Code Command Palette and reload the window. This will delete all cached bundles and often resolves duplicate‐bundle errors.
• Manually remove the server folders under:
  • ~/.vscode-server/extensions/vscjava.vscode-java-test-*/server
  • ~/.vscode-server/extensions/vscjava.vscode-java-debug-*/server
    then restart VS Code to force a fresh install of those bundles.
• Make sure your Java Test and Debug extensions are on compatible versions (avoid mixing pre-release and stable builds).
• If the problem persists, uninstall and reinstall the Java Test and Debugger for Java extensions.

Other references with low confidence

• Update jar version and load bundle throw exception (Update jar version and load bundle throw exception vscode-java-debug#54): a similar OSGi BundleException when installing a debug plugin JAR. Users resolved it by clearing the extension cache and ensuring matching JAR versions.
  Update jar version and load bundle throw exception vscode-java-debug#54

The team will respond to your issue shortly. I hope these suggestions are helpful in the meantime. If this comment helped you, please give it a 👍. If the suggestion was not helpful or incorrect, please give it a 👎. Your feedback helps us improve!
