* WARNING: this function returns global and local references. This can be
* figured out using GetObjectRefType. Though, when this function is called
* from within a Java context, the local ref will automatically be cleaned
* up. If this is called outside of a Java frame,
* PushObjectFrame/PopObjectFrame can simulate this automatic cleanup. The
* platform provides ScopedLocalFrame as an RAII object for this.
