RFR(S): JDK-8016644 - Improve UnsupportedClassVersionError message

[Christian Thalinger]

I respectfully disagree.  If I want to e.g. run all tests in interpreted mode for whatever reason (maybe there is a bug in the compiler and I want to see if it happens in interpreted mode too) then I want ALL tests to run with the flags I specify.  No matter what they do.
