NullPointerException in JDTLanguageServer$2.run(JDTLanguageServer.java:332)

[guw]

Found this in the log:

!ENTRY org.eclipse.core.jobs 4 2 2023-10-27 13:30:56.284
!MESSAGE An internal error occurred during: "Initialize workspace".
!STACK 0
java.lang.NullPointerException: Cannot invoke "org.eclipse.jdt.ls.core.internal.handlers.WorkspaceDiagnosticsHandler.publishDiagnostics(org.eclipse.core.runtime.IProgressMonitor)" because "this.this$0.workspaceDiagnosticsHandler" is null
	at org.eclipse.jdt.ls.core.internal.handlers.JDTLanguageServer$2.run(JDTLanguageServer.java:332)
	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:63)

This happens during execution of tests in VS Code. Is there something missing in the setup?

This might be triggered because of a parallel shutdown.

Can you provide steps to reproduce?
