ConfigObserver was causing a memory leak ---------------------------------------- Key: JBWS-1833 URL: http://jira.jboss.com/jira/browse/JBWS-1833 Project: JBoss Web Services Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: jbossws-1.2.1 Environment: https://na1.salesforce.com/50030000003iZKa Reporter: Heiko Braun Assigned To: Heiko Braun Priority: Critical Fix For: jbossws-2.0.1.SP2 ConfigObserver becomes a possible memory leak: I think the leak is created through the Observable pattern that's used between EndpointMetaData(Subject) and CommonBindingProvider(Observer): For each invocation we create a ServiceEndpointInvoker. Each invoker will be associated with a BindingProvider. This links the CommonBindingProvider to EndpointMetaData through the Observer pattern. The EndpointMetaData is kept in the registry. IMO this is result in a memory leak. I'll need to verify this assumption. But basically you could monitor a deployed EndpointMetaData#configObservable.countObservers(). If the above statement is true is will increase with every request that's being processed.
