I don't have a strong objection to the proposed change but the check 
seems to be only useful to catch the case where someone is running these 
jdk6 or jdk7 tests on jdk5. It was useful that it caught the problem 
with the usage message but I think the simplest fix is to just remove 
lines 55 and 58-65 from both tests.
