You need to go find the IBM Errata sheet for the chip in question.
It's at
http://www-306.ibm.com/chips/techlib/techlib.nsf/products/PowerPC_405EP_Embedded_Processor
I believe the same problem might be present there, renamed CPU_210.

The gcc bug report for this was http://gcc.gnu.org/PR7383
My comments there make me think that maybe I did try to fix
the Java part of the problem, but I never tested that.
Only now am I testing gcj at all, and I don't use the ppc405 anymore
(I switched jobs).
