Jeff just noted that Liferay seems to take an abnormal amount of

I just redeployed the console twice and got an OutOfMemoryError.
When working on the console for 1.1, I could redeploy dozens of
times.
I think we've introduced a pretty serious memory problem between 1.1
and now. I know we're close to the deadline, but I think we ought to
investigate this before shipping 1.1.1.
OK. I've found the cause -- it's RC 425160 (http://svn.apache.org/
viewvc?view=rev&revision=425160). Looks like we were running out of
PermGen space. This change roughly double the number of classes
created by G on startup. I could only deploy/undeploy DayTrader once.
After reverting the change, I've run well over 100 deploy/undeploy
cycles. We're leaking two instances of
'EDU.oswego.cs.dl.util.concurrent.LinkedNode' per deploy/undeploy,
but that's only 32 bytes...
I haven't confirmed, but I saw evidence that it was at least part of
the DWR leaks that Jeff G reported.
Here's the Jira associated with the above change -- http://
issues.apache.org/jira/browse/GERONIMO-2204
Since the change is optional, I'm reverting the commit. I think we
can safely leave out of 1.1.1. Can discuss how we want to fix, later...
