Yes.  That is correct.  We don't need more frameworks that hinder 
getting to the java command line for the class file.  It's time 
consuming enough with jtreg.

Can you repost the whole webrev to hotspot-dev ?  I didn't see the 
original to see why these tests require the testng framework and cannot 
be written as simple regression tests.  If they have to be very complex, 
maybe they belong in a different test directory that has support and 
tolerance for this complexity.  Maybe you can write a small regression 
test for the hotspot/test/runtime test and put the rest somewhere else.  
Again, this is in the abstract.  I don't have the webrev.
