RFR(XS): 8251316: Sanity check the JDK under test before running tests

[David Holmes]

Seems reasonable - at least until jtreg is fixed.

Where does the hs_err file from a crashing VM end up?

Thanks,
David

To make it faster to diagnose the problem it would be useful to do some sanity checking of the JDK before invoking jtreg.
