Do you know why this happens?  Is it a bug in the way (FreeBSD and Linux) i386 
binaries are compiled?

I tried that too, which is why I thought it was bizarre.  Here is my "result 
matrix" for java -version

			Athlon 64	Sempron 64
linux_base		fails		runs
linux_base-rh-9		runs		not tested
FreeBSD/i386 jdk4	fails		fails

The FreeBSD package was actually compiled on 6-STABLE dated a few weeks after 
6-REL, whereas the two amd64 machines are running 6-RELEASE.  If that is not 
the issue, it was fubarred from the start.
