    Attachment: rf.patch


I would suggest the attached patch to fix this leak, for me it seems to resolve the leak and not introduce any regression. However, somebody more familiar with richfaces code should review it. The idea is to delay Meteor creation until it is explicitly used, in particular after session validity check.

> Hello,
> I did an upgrade from RF 4.3.3.Final to 4.3.4.Final and the application started to crash with 'Out Off Memory' errors. I changed the POM back to 4.3.3.Final and the problem is gone.
> I also started seeing this message lot's of times:
> {{WARN  org.atmosphere.cpr.AtmosphereResponse - Committed error code 400}}
> I don't know if that has anything to do with the error. I set {{org.atmosphere.cpr.sessionSupport}} to {{true}} and I did not see the message again. But still the application went out-of-memory.
> In the crashed system heap dump I see a lot of:
> - AtomicBoolean (751.000, 15.0MB)
> - ConcurrentLinkedQueue
> - AtmospereRequest$Builder (60.042, 13.8MB)
> To me it looks like it has something to do with Atmosphere. Any ideas?
> Thanks,
> Milo van der Zee
