This way I managed to reproduce the problem after some rounds of clicking, 
using Snow Leopard both with the native "Mac OS X" and "Nimbus" look & 
feel. Mountain Lion appears to work, at least I did not see anything bad 
after trying the same 4-5 times longer than on Snow Leopard.

So it might be just bad luck of Java 7 on Snow Leopard.  Oracle says it 
does nothing against it nor for it.  So if Java 7 happens to work on what 
Apple considers legacy already, it is mere luck.
