Hi @CsCherrYY, 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

No existing documentation or GitHub issues directly address adding multi-threading support to the Java Language Server. To move forward:

• Open a dedicated feature request against the Eclipse JDT LS repository, where core threading and request handling are implemented:
  • URL: https://github.com/eclipse/eclipse.jdt.ls/issues/new?template=feature_request.md

• In your request, describe the specific operations you’d like to parallelize (e.g., code completion, diagnostics, indexing) and any performance metrics or use cases (large projects, CI environments).

• As a temporary mitigation, note that some long-running tasks (like indexing) already run in background threads within JDT LS; consider:
  • Enabling incremental build/configuration by setting java.configuration.updateBuildConfiguration to automatic or interactive in your VS Code settings.
