Is it possible to convert all failures of this form into a C++ test case
with -fnon-call-exceptions?  If so then at least there is a way to add
regression tests.

Steven> Is it possible to build and test java without all of libjava?

As far as I'm aware, not at present.  I think even the minimal possible
subset of libjava is pretty big, on the order of hundreds of classes,
IIRC.
