Mike Noordermeer commented on CXF-5087:
---------------------------------------
I believe this bug is missing a fix version 2.7.6. It does seem fixed judging
from the source tagged 2.7.6/2.7.7.
> ThreadLocal: BusFactory.threadBus is never removed, generates permgen out of
> memory error after some redeployments

> Key: CXF-5087
> URL: https://issues.apache.org/jira/browse/CXF-5087
> Project: CXF
> Issue Type: Bug
> Components: Bus, Core
> Affects Versions: 2.7.5
> Reporter: Rene Preissel
>
> The ThreadLocal BusFactory.threadBus is created in the constructor of the
> CXFBusImpl and removed in the shutdown()-method.
> But in an application server environment (e.g. JBoss7) with thread pools the
> constructor and the shutdwon()-method are invoked from different threads and
> therefore this ThreadLocal is never removed.
> Issue CXF-2164 and CXF-2985 do already discuss this topic and assume that
> this bug is fixed, but there is still this dangling ThreadLocal. I proved
> this in a JBoss7.1.1.Final environment.
> I don't know the reason for having this ThreadLocal for the whole lifetime of
> the bus. From my point of view a ThreadLocal should only exist for the
> lifetime of one request. At the end of the request, when the thread is given
> back to the pool, the ThreadLocal must be cleared.
