>Environment:
FreeBSD 4.9 (kernel compiled by myself with USER_LDT, i686)... worked on FreeBSD 5.2.1 (kernel compiled by myself, i686)
my machine is an Intel Pentium II with 160 MB
I'm not working on it at the moment so I cannot paste the exact uname -a output...sorry.
>Description:
JBuilderX is a java integrated environment for linux distributed by borland. It uses the included jvm 1.4.1 for linux.
It worked fine on 5.2.1, on 4.9 I can install it, but when I run it I get the message "Cannot get information from pid..." on std output.
I have linprocfs mounted rw...
>How-To-Repeat:
Install FreeBSD 4.9. Install JBuilderX for linux. Run it... 
>Fix:
I really need help :)
