Thanks for the reproducer.  Looking into it a bit, it smells like a 
reincarnation of an ages-old phenomenon where the JVM garbage-collects 
objects "too aggressively" (i.e., with the object still nominally on the 
call stack, but optimized away) and we thus send a release call from 
Java URP to binary URP too soon.  I'll look into it further.
