Example: JBossAS5's shutdown operation leaves JBoss AS UP. That's... non-optimal, at least. See the screenhost if you like.
Funny, I was recently also thinking about this. Same for operations that e.g. create new child resources.
The support for this has been implemented in the jshaughn/avail branch and applied to AS and AS5 plugin's operations. Other plugins still need to be reviewed.
All of our relevant plugins have been updated and the avail branch is in master.
Bulk closing of items that are on_qa and in old RHQ releases, which are out for a long time and where the issue has not been re-opened since.
