Of course, creating handles to instances and passing those handles around creates extra dependencies between the environment which created the handle, and the environment consuming it - again, not saying it's an impossible problem to solve, but more thinking is definitively required before we cross that particular bridge.

Yes, in my response I “right sized” his request to
providing an indirect handle instead of a direct
pointer into the Java heap.  Direct pointers are
much harder, too hard IMO.  Handles are easier:
you just have to deal with all the nit-picky
bookkeeping problems, including those I sketched.
