When building and testing Octave using gcj as the JRE, building succeeds but
crashes at runtime or when running the test suite. On Debian x86-64,

$ ../configure JAVA_HOME=/usr/lib/jvm/java-gcj
$ make all
$ make check
  build-gcj/libinterp/octave-value/ov-class.cc-tst ............panic: Aborted
-- stopping myself...
octave exited with signal 6

Under gdb, the backtrace shows the error is occurring inside of the
JNI_CreateJavaVM function.

I wonder if something could be done in the configure script to try to
initialize the JVM from a test program and try to catch this error there? I'll
see if I can get the same crash to occur with a simple stub test program.
