I am getting exactly the same with
ktruss java -version
(well, the addresses are different, if that matters - I think not).
I can write down the output from bt if necessary - this machine does

try the same under VMware and get the output there.
With a slightly earlier verson of the kernel it froze itself trying to
open an entry under /emul/linux/proc.
