RFR(xs): 8224710: [TESTBUG] dynamicArchive/ExcludedClasses.java test failed in tier6 testing on Windows

[Jiangli Zhou]

Hi Calvin,

Test fix looks reasonable. It would be a good idea to also fix the
original error message and the check in the test so it's grammatically
more correct:

"DynamicDumpSharedSpaces is not supported ..."
                                                  ^

Best Regards,
Jiangli
