I am not convinced this is needed. Does anything in the JNI prohibit the
following implementation:
* Locals refs and global refs are the same. When either refers to an
object, the ref is just a pointer to the Java object.
* NewGlobalRef is an identify operation.
* DeleteLocalRef and DeleteGlobalRef do nothing.
I'm not seeing how a valid JNI program can not work given this
implementation. I'm assuming the conservative GC will find
both local and global references assuming it normally scans
C static and local variables. Is that not the case?
