Thanks for testing. This leaves us with two options: some general JDK 
change which brought some latent issue to the fore, or some specific 
regression in the linker support. On top of my head the latter doesn't 
make much sense - since the new panama changes only affect the API, not 
the VM internals.

But I'll keep testing on my end.
