So, if you would like to work on that (which would make me happier),
then apply the attached patch, then:

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.
Ah, not quite. Should be fixed now with <http://cgit.freedesktop.org/libreoffice/core/commit/?id=3766f2a0d3bc50919366b0e43f5ee8c814019c8b> "Finalizers must not access UNO objects" (see there for details).
