The tests from PartOnTopManagerTest running local on windows often get stuck. Logging a lot of errors. Feels like they get stuck in recursive error handling:


!ENTRY org.eclipse.e4.ui.workbench 4 0 2021-11-01 15:14:49.903
!MESSAGE Internal Error
!STACK 0
org.eclipse.e4.core.di.InjectionException: Unable to process "WorkbenchWindow.model": no actual value was found for the argument "MTrimmedWindow".

...

logged Stacktraces are way to long to paste it in a bug message.


I got no idea what those tests doing or why they get stuck, but i often see platform ui builds timing out and may be that is related.

Help wanted.
