The builds involved do not generate the classes_coh.jsa file, but CDSConfig still sets the default archive path to classes_coh.jsa if UseCOH is enabled.

I'm not sure if the bug is in the test or CDSConfig - the latter seems to assume the classes_coh.jsa must exist which is not the case.

I think the test is no longer valid and should be deleted. There's no way to tell if "a default CDS archive should exist for a $JAVA_HOME". This is a build time decision whose only effect is whether a given classes??.jsa exists in $JAVA_HOME or not. The original summary "JDK platforms/binaries do not support default CDS archive should not contain classes.jsa in the default location" seems vacuous: "a file that does not exist should not exist", so there's really nothing to test for.

After the fix for JDK-8341533, by default, JDK built within Oracle will not generate the compact object headers CDS archive (classes*_coh.jsa). I think in the test in the case that the expected CDS archive doesn't exist, it should check if the UseCompactObjectHeaders is enabled and the expected CDS archive file name ends with "_coh.jsa", just throws a SkippedException.
