Bharath Ganesh resolved CXF-1621.
---------------------------------
Resolution: Fixed
Fix Version/s: 2.0.7
2.1.1
http://www.nabble.com/Memory-Leak-at-WSDLManagerImpl-td17579537.html
The schemaCacheMap will now always have a weak value (This will be done by
putting a WeakReference of the
ServiceSchemaInfo in the map).

> Key: CXF-1621
> URL: https://issues.apache.org/jira/browse/CXF-1621
> Project: CXF
> Issue Type: Bug

> Fix For: 2.1.1, 2.0.7

>
> The schemaCacheMap in WSDLManagerImpl has a weak key - WSDLDefinition and
> value ServiceSchemaInfo. A key,value pair is inserted into this map while
> building a service. The entry is never explicitly removed from this map.
> Since the map is a WeakHashMap, it is assumed that when the key
> WSDLDefinition is weakly referenced, the entry would be removed from the map.
> But it is seen that the value ServiceSchemaInfo(the value) holds on to a
> SchemaInfo which in turn holds on to the ServiceInfo, which holds the
> WSDLDefinition through the AbstractPropertiesHolder.
> This would mean that the value of the CacheMap always strongly refers to the
> key, which would mean the entry would never be removed from the map.
> "The value objects in a WeakHashMap are held by ordinary strong references.
> Thus care should be taken to ensure that value objects do not strongly refer
> to their own keys, either directly or indirectly, since that will prevent the
> keys from being discarded"
> This would mean ServiceInfo, OperationInfo, BindingInfo, WSDLDefinition would
> all stay in the VM even after the endpoint is stopped.
