I've seen here
http://www.cokeandcode.com/XMLVM-OpenGL-Support-Patch-Commited
which talks about annotations.

I looked at the source code and I saw this, in file  
XMLVMNoAutoReleasePool.java
@Retention(RetentionPolicy.CLASS)
so, is there any way to "optimize" GC with annotations?

And, one more thing, is there a way to force send an object to  
oblivion, e.g. when we have cycle dependencies like the one mentioned  
above (and I just want to free some memory) ?
