It looks like gcj-dbtool printed its result on stderr instead of
stdout, so aot-compile-rpm read nothing from it. Did something
change in gcj-dbtool?

Cheers,

No. If there's a message on stderr, it's an error message. We
need to know what that error message is. I just ptrace'd gcj-dbtool
in gcj 4.3.1 and got

[pid 23950] write(1, "/usr/lib64/gcj-4.3.1/classmap.db"..., 33/usr/lib64/gcj-4.3.1/classmap.db
) = 33

The only other thing I can think of then is that Python's os.popen()
didn't capture stdout properly. There's nothing in aot-compile-rpm
itself that would write "/usr/lib64/gcj-4.3.1/classmap.db" to either
stdout or stderr.

Cheers,
Gary

Yeah. We need to strace aot-compile-rpm at this point to see what it's
doing. Orion, is there some way I can logon to this box?

This is probably the popen() broken on xen kernels bug. I'll resubmit
my build.
