Bundles contributed to JDT-LS runtime fail to stop gracefully

I open a project like eclipse.jdt.ls or even something like lemminx which is unrelated (no javaConfig.json). Everything works fine, but on shutdown, I notice that the JDT-LS standard client doesn't shutdown immediately. That's odd. On a "simpler" project I tried and none of this seems to happen (shuts off immediately). So now it's just time for the parent process watcher to trigger and handle the cleanup. When it does, I see the following in the logs.

I can try to reproduce this after we solve https://github.com/redhat-developer/vscode-java/issues/2471 . It could be a symptom of the language server not shutting down immediately.

[rgrunber]

The stacktrace from above still happens on shutdown. Only this time it is preceded by a proper shutdown.

I tried eclipse.jdt.ls project with vscode-pde and the latest vscode-java pre-release version v1.7.2022052804 , closing VS Code window and I only see a shutdown message in .log. No exit message and other exceptions.
