Interestingly, Andrew's example is incorrect. You also need
JavaPointer<jobjectArray>. I guess this method isn't as easy as it
looks at first.

Yeah, I agree. What sort of performance penalty can we expect from
that?
As a practical matter, using JavaPointer means going over about 60KLOC
making this change. That will be fun.
