Description
OBJ-C Garbage Collector was deprecated in 10.8 and it's not supported any more. It is actually not used in JDK, however there are some legacy references to it in our code like overridden finalize method or CFRetain/release pattern. All this could be safely removed.
Comments
It's not about Java finalize, but about native finalize. We have quite a lot of commented out finalize overrides and 2 real overrides in Accessibility code.

And I about "like overridden finalize"

I'm talking about the occurrences of this pattern: if (object) { CFRetain(object); // GC [object release]; }

Note that CFRetain is used to increment a counter, when we have a reference from java to native. Otherwise we can get a live java object and deallocated native.
