Well, we've been waiting for you to bring your expertise to bear on this
issue, André :)

I'd be surprised if this was the problem: Carl is installing Sun's JRE,
which should have everything it needs. He says he's not playing around
with any native code, so I wouldn't expect anything to be incompatible.
I'm not saying it's impossible... just that I'd be surprised if it's the

I'd think you'd get something other than a SIGSEGV anyway... attempting
to load an incompatible library ought to get you some other error...
though I'm not sure which. You could probably try to force that to
happen with something like this (in Java, of course):


...and see what happens. I don't have a library of the wrong
architecture laying around right now. I tried to load some random file,
and I got an UnsatisfiedLinkError, but that's at the Java level. I have
no idea what would happen if the native X11 graphics library was being
loaded by the JVM and wasn't compatible...

It's possible. If SSL is in use, consider "downgrading" to the pure Java
connectors (i.e. no APR... enjoy re-configuring Tomcat to use the
different-style SSL configuration) to see if that clears things up.

strace would indicate that this was the problem if you had multiple
runs: the openssl libraries would always be in the mix of the stack trace.
