It also works with OpenJDK7, but there isn't a port of that in the ports
tree.

I tried openjdk jstack against diablo-jdk and it doesn't work, so
i just tried using tomcat with openjdk and when running jstack i
get the following error:
yac# /usr/local/openjdk6/bin/jstack -F -l 89291

Also if i try to use it without -F i get the following error:
/usr/local/openjdk6/bin/jstack 89291
89291: Unable to open socket file: target process not responding or
HotSpot VM not loaded
The -F option can be used when the target process is not responding
Do you have any ideas on what could be wrong?
Thanks a lot.

Is there any place where i can download an unstable port or something
like that just for testing? or any expected date on when it will arrive
to the ports tree?
Regards.

Do you run jstack as the same user as the java process?
