I just thought of something... You can test whether this problem is
related to the JITC's code-generation or not by using the -Xint option to
the 'java' command (type 'java -X' for a summary). The -Xint should
prevent the JITC from compiling any of the bytecodes to native code, and
may affect whether a 64-bit divide opcode is used.

I say "may affect" because there might be code in the JVM interpreter
itself that auto-senses a G5 and then chooses a code-path accordingly.
That is, the plain interpreter could use 64-bit divide. I don't have the
JVM source, so I can't say whether it does this or not, only that it's
technologically possible.

In any case, taking the JITC out of the test might help narrow down where
the failure lies, and if it works with -Xint, could represent a
work-around. As a work-around, it will run about 10X slower, but that's
arguably better than not running at all.
