Memory Leak in WSDLManagerImpl - SchemaCacheMap
-----------------------------------------------
Key: CXF-1621
URL: https://issues.apache.org/jira/browse/CXF-1621
Project: CXF
Issue Type: Bug
Components: Core
Affects Versions: 2.0.6, 2.1
Reporter: Bharath Ganesh
Assignee: Bharath Ganesh
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.
