jdt.ui.tests.refactoring DNF since I20240331-1800

[iloveeclipse]

See https://download.eclipse.org/eclipse/downloads/drops4/I20240331-1800/testResults.php and all following builds.

Note that the build logs for all JDT UI related bundles is multiple megabytes, while usually below one MB:

old log from https://download.eclipse.org/eclipse/downloads/drops4/I20240330-1800/logs.php#console

In the logs I see no real errors, but tons (~ 15.000 times) of stack traces reported by UI freeze monitor on JavaProjectHelper.delete() that hangs in org.eclipse.swt.internal.ole.win32.ITaskbarList3.SetOverlayIcon(ITaskbarList3.java:31) (why UI freeze monitor is not disabled during tests???):

I've checked stack traces, they all look "innocent" and doesn't point to any recent change in the code. I assume Windows test machine is in some bad state and needs a restart.

Fixed by machine restart
