RFR: 8297977: vmTestbase/nsk/stress/except/except012.java fails with unexpected Exception

[Coleen Phillimore]

These vmTestbase/nsk/stress/except tests all allocate enough memory to get an OutOfMemoryError then try to throw an exception for a variety of error conditions.  The tests pass (or all say it's "Skipped ...") if that throws OutOfMemoryError, which all the tests do.
Only except001.java did something useful - called a function that gets OOM reflectively then tests that it got an InvocationTargetException so I moved that to runtime/reflect/ReflectOutOfMemoryError.java.  This change removes the rest.

I couldn't reproduce the original failure in except012.java, which gets another exception (not OOM or ThreadDeath).
