Description

Always see it dumps the threads in the group to stdout.

This is an example

java.lang.ThreadGroup[name=PEWorkerGroup,maxpri=10]
    Thread[HFileArchiver-1,5,PEWorkerGroup]

I guess the problem is that we create a thread pool when executing a procedure so the thread pool will inherit the thread group.

Not a big problem but still a bit nasty...
