Or it might be a NIS problem. I had a similar problem
after upgrading libc, and it turned out that I had a
file lying around /var/yp/binding/XXXX.2 (XXXX replaced
with my old NIS domainname). After removing this file,
various java programs and other things went a lot
faster.
Have you tried using strace(1) to see what rmic is up to?
