I don't know at this level if it is survivable or not.  The native
contract is to call that function, if I can't then I'll just throw an
exception.  If it is handled as survivable in the Java code then fine,
otherwise it will cause a sane termination.

I don't know the cause, so the exception will just describe the effect.
