Hi @devhamzat, 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.

Possible Solutions

• Update your Java extensions to compatible, latest versions:

  • Ensure Language Support for Java™ by Red Hat and Debugger for Java are both installed and up-to-date. In issue #1342, the fix was to bump Red Hat’s Java extension beyond v0.64.1 to match the debugger version.

• Clean & reload the Java language server:

  1. Open Command Palette (⇧⌘P / Ctrl+Shift+P).
  2. Run Java: Clean Java Language Server Workspace and choose Reload and Delete.

• Verify your launch.json is targeting a valid mainClass and that your java.home / JAVA_HOME settings point to a supported JDK.
