RFR(S): 8197906: Enable CDS mode execution of jtreg tests via make

[Igor Ignatyev]

[1] and [2] are equivalent for cygwin, but it doesn't mean they are equivalent JVM. I recall there were some problems when cygwin paths passed to JVM. so to be on the safe side, I'd use mixed or windows path to the archive in JVM flags.

Thanks,
