Hi Sergey,

I agree if this change goes to 8u as the least risky thing we can do now.

For 9 I'd prefer to fix the root cause of the problem, which is related 
to the wrong cast of e.g. AwtList::_IsSelected from (jboolean 
(*)(void*)) to (void *(*)(void *)) - we simply should have never 
performed such a type cast because it's wrong.

Alternatively, we could push your fix to 9 now so as to enable its 
back-porting, and then file a new bug against 9 to fix this issue 
properly. If you choose this way, please provide us with the new bug id 
and consider the current fix approved then.

best regards,
