Java support for jstack

[Victor Balada Diaz]

Hello,

I'm trying to use jstack in a FreeBSD 7.1-RELEASE-p7 amd64 with
diablo-jdk-1.6.0.07.02_3 but i always get the following error:

$PID: no providers installed

I saw a mail in 2007 asking about what would be needed to make it
work, but no answers. Is there any work in progress to make jstack work?
What's needed and how can i help?

Thanks in advance.
Regards.
