Seems I can't ececut anything from java.

if I type:

/opt/ibm-jdk-bin-1.4.2/bin/javac

I only get

"Killed"

on commandline.

When I use strace, the end is:

My kernel-version  is 2.4.31, with grsecurity patches (PAX...), perhaps 
it has something to do with that?

I have never used Java on Linux, so perhaps I'm missing something.

It's strange, I can execute "java", but "javac" gets killed somehow.
