I think I agree with what @iklam said in JBS - this test seems to have no purpose now. I can't tell what exactly it is trying to check for. Depending on the runtime flags the name of the expected "default archive" is different, but it is not mandatory to have an archive file present - unless it is the plain classes.jsa one ?

And what does `Platform.isDefaultCDSArchiveSupported()` actually mean now we have the optional COH archive?
