We recently saw issues with logger usage in sun/java2d/marlin/ClipShapeTest.java, see JDK-8369911 .
[~rriggs] commented on this
"Loggers need to be stored in statics or they get GC'd and later requests get a new instance (without the added handler).
It is surprising not to be have been a problem since it was added in 2018."
But there seems to be problematic logger usage in other java2d tests too; maybe the logger usage should be revised in those tests .
