The JVM is not supposed to be loaded unless it is actually needed.  Is
there some test that runs prior to the one that fails that causes the
JVM to be loaded?  Can you simply skip that set of tests (delete them)
and see if that avoids the problem?  If so, then that would also be
consistent with the observation that the tests fail when running make
check (which presumably causes the JVM to be loaded) but they don't fail
when running the quadcc test by itself in a new Octave session.
