The following test failed in the JDK20 CI:

This failure happened in jdk-20+10-535-tier4 and the fix for the
following bug:

JDK-8169187 [macosx] Aqua:
java/awt/image/multiresolution/MultiresolutionIconTest.java

was integrated in jdk-20+10-523. The fix for JDK-8169187 is
for a macOSX bug, but the ProblemList update also removed the
entries for non-macOSX platforms:

-java/awt/image/multiresolution/MultiresolutionIconTest.java 8169187,8252812 macosx-all,windows-all,linux-x64

I'm not sure why that was done.
