NullPointerException in Jakarta EE Server Initialization

When clicking on variables in a Java project, an error occurs in the Jakarta EE server initialisation process. The error message indicates a NullPointerException during the execution of the org.eclipse.lsp4j.Diagnostic.getCode() method, specifically when trying to invoke org.eclipse.lsp4j.jsonrpc.messages.Either.getLeft(). As a result, the request textDocument/codeAction fails repeatedly, showing error code -32603. Additionally, in some cases, there are warnings for unmatched cancel notifications and errors indicating that the client is not running.

Environment

• Operating System: MacOS (Ventura 13.4)
• JDK version: temurin-11
• Visual Studio Code version: 1.80.1
• Java extension version: Latest at this time (1.20.0 I believe)

Steps To Reproduce

1. Build project, open file.
2. Click somewhere within the code.
3. See error.

Current Result

Expected Result

No errors.

Additional Informations

java-server.log

Empieza reproduciendo el fallo con el entorno de MacOS, JDK, VS Code y la extensión de Java indicado, y después inspecciona java-server.log. Sigue el recorrido de textDocument/codeAction alrededor de org.eclipse.lsp4j.Diagnostic.getCode() y Either.getLeft(). Se considera terminado cuando hacer clic en el proyecto Java ya no produce la NullPointerException ni errores -32603 repetidos.
