Hi Pavel,

Thank you for your testing efforts!

It looks like the test does not actually belong in JDK 6, and should 
fail there - please refer to the comment section in the very beginning 
of the test source. [1] shows that the fix for which the test is 
written, has been available since 7b03, and isn't present in 6 at all. 
Since 7b20 included all the tests present in 7b03, the test got to 
OpenJDK 6 as well [2]. Weird, I agree.

I doubt if we want to back-port [3] though (which is the actual fix for 
[1]). Therefore, I think the test had better be removed from OpenJDK 6.
