Amichai Rothman updated CXF-5188:

    Summary: Leaks in ServiceImpl when stopping/restarting bundles  (was: Possible memory
leak in ServiceImpl)
> Leaks in ServiceImpl when stopping/restarting bundles

>                 Key: CXF-5188

>             Project: CXF
>          Issue Type: Bug
>    Affects Versions: 2.7.2
>         Environment: Karaf 2.3.2, DOSGi 1.6.0-SNAPSHOT
>            Reporter: Amichai Rothman

> I've been looking at VisualVM heap dumps after restarting some custom bundles in Karaf
and noticed the stopped services (exported via DOSGi) linger in memory and are never garbage
collected (screenshot attached, StoreServiceImpl being the lingering custom service). Browsing
through the instance hierarchy from the snapshot I found something suspicious - org.apache.cxf.endpoint.ServiceImpl
registers the ManagedEndpoint with the ServerLifeCycleManager, but doesn't seem to unregister
it when the instance is destroyed. Could this be the memory leak preventing the old bundles
from being collected?
