Jenkins kills the test process.

Thanks for opening this. I'm in the middle of releasing JDT-LS via. https://ci.eclipse.org/ls/job/jdt-ls-master/1516/ and have also seen some occasional failures in PRs.

Looking back, the first failure I saw happened around these commits :

https://ci.eclipse.org/ls/job/jdt-ls-master/1504/ (Tycho 3.0.0 update)
https://ci.eclipse.org/ls/job/jdt-ls-master/1505/ (4e4406a)

@rgrunber #2360 is ready for review. There were many gradle daemons and CI kills the job. The PR fixes it.

I have also added -Dorg.gradle.daemon.idletimeout=300000 (5 minutes) to the jdt-ls-pr and jdt-ls-master builds. Default is 10800000 (3 hours) - https://ci.eclipse.org/ls/job/jdt-ls-pr/jobConfigHistory/showDiffFiles?timestamp1=2022-11-28_02-44-12&timestamp2=2022-12-01_12-25-20
