Yep - this is same issue as the one I was mentioning:

http://bugs.sun.com/view_bug.do?bug_id=6650759

The fix that caused this was attempted in the JDK 7 repo - I then 
updated it with the help of Alex as this area required a bit of a JLS 
cleanup, as it was the JLS that was mandating this particular failure. 
That's why the code in JDK 7 works correctly, as it take advantage of 
the new spec goodies. As for JDK 6 (closed) the 'fix' was simply not 
there and the old compiler behavior was more powerful than the one 
described in the spec, which allowed this kind of examples to compile.
