   Hi ABDERRAHIM TALIBI (@abdertalibi-gif), 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 workarounds

   • Clear the installer cache and retry:

     • On Linux: remove ~/.vscode-java-installer (or %TEMP%\vscode-java-installer on Windows) and reinstall the Java Extension Pack.
     • Or delete the corrupt VSIX in your extensions folder: rm -rf ~/.vscode/extensions/vscjava.vscode-java-pack-* then reinstall.

   • Install the pack manually via CLI:

     code --install-extension vscjava.vscode-java-pack --force

   • If you’re using Code - OSS (which lacks Microsoft’s signing key), switch to the Open VSX registry by adding to settings.json:

     "extensionsGallery": {
       "serviceUrl": "https://open-vsx.org/vscode/gallery",
       "itemUrl": "https://open-vsx.org/vscode/item",
       "controlUrl": "https://open-vsx.org/vscode/control"
     }

   • Collect detailed logs as requested (F1 > Open View… > Shared) or attach ~/.vscode-java-installer/log.txt to help diagnose further.
