Hi @Eskibear, 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.

Suggested fix

This error is usually caused by the language server trying to resolve a snippet‐type completion. You can work around it by ignoring snippet completions in the resolve handler, as shown in:

• Quick fix: skip completionItem resolution when CompletionItem.kind == Snippet
  completionItem/resolve on Snippets throws exception eclipse-jdtls/eclipse.jdt.ls#675

Next steps

• Update to the latest Eclipse JDT LS/VS Code Java extension, which may include a fix for snippet resolution.
• If the problem persists outside of snippet proposals, please file a new issue with reproduction steps.
