Hi @ZhengJun003, 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.

This error is coming from VS Code’s UI layer when you toggle the Developer Tools, not from the Java extensions themselves. Suggestions:

• Update VS Code to the latest version. There have been various fixes around DisposableStore in recent releases.
• Update the Java extensions (Language Support for Java and Java Debugger) to their latest versions.
• Try reproducing without opening Developer Tools—clicking the "Run | Debug" code lens should launch the debugger without errors.
• If the issue persists, please file it against the VS Code core repository: https://github.com/microsoft/vscode/issues/new?title=DisposableStore%20error%20in%20UI
