Daniel Kulp resolved CXF-2756.
------------------------------
Resolution: Invalid
Fix Version/s: Invalid
I'm going to close this as invalid as it looks like it's a JBoss issue. CXF
doesn't scan anything or redploy/restart anything. Thus, this is likely an
issue in the jboss integration layer and would need to be reported to them.
> OutOfMemoryError with many service endpoints

> I am deploying an EAR in JBoss which exposes many (approx. 120) endpoints,
> each of those publish a simple WSDL (2 services with 1 parameter) - demo
> attached, if necessary I can add a private attachment with the real world EAR.
> When invoking these service endpoints, CXF always scans the entire EAR and
> (re)builds the service endpoint registry.
> Performance with many (10-20) concurrent service calls degrades and memory
> consumption increases steadily, ultimately leading to an OutOfMemoryException
> in JBoss. It seems the endpoints cannot be found in the cache and so the
> entire registry is rebuilt.
> In a simple test it showed that simply displaying the service endpoints
> exposed WSDL is sufficient to trigger the problematic behaviour:

> Metro does not show this behaviour and reacts very fast with minimum memory
> consumption, but we cannot easily switch the entire web service stack at this
> time and I don't believe CXF has such a problem with many service
> endpoints... however since even calling the WSDL from JBoss' web interface
> triggers the problem, the app cannot be blamed...
> Memory analysis with Eclipse MAT shows that the class
> org.apache.cxf.common.util.CacheMap grows excessively large, will attach some
> screenshots (also tested with jVisualVM) and logs later.
> Possibly related bugs:

> performance of repeated calls to jaxws.Service.createPort is poor, jaxb
> context is created every time
