[jira] Commented: (AXIS-2505) memory leak in wsdl generation
[ https://issues.apache.org/jira/browse/AXIS-2505?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12491112 ]
Bjorn Townsend commented on AXIS-2505:
--------------------------------------
I patched the Axis trunk with this fix and ran the test suite against it -- looks like it doesn't break anything, and I've verified that it seems to fix the memory leak.
> memory leak in wsdl generation
> ------------------------------
>
> Key: AXIS-2505
> URL: https://issues.apache.org/jira/browse/AXIS-2505
> Project: Axis
> Issue Type: Bug
> Components: WSDL processing
> Affects Versions: current (nightly)
> Reporter: Christopher Sahnwaldt
> Priority: Minor
>
> There's a memory leak in org.apache.axis.description.JavaServiceDesc.setDefaultNamespace():
> the method adds the given namespace to an ArrayList. This method is called from
> org.apache.axis.wsdl.fromJava.Emitter.init(), which in turn is called from
> org.apache.axis.providers.BasicProvider.generateWSDL() each time wsdl is generated for a service,
> i.e. whenever .../ServiceName?wsdl is invoked.
> To reproduce start an Axis server in a debugger, invoke ...?wsdl from a browser a couple of times for
> a certain service, and check the instance variable namespaceMappings in the JavaServiceDesc
> for that service. It grows by one element each time the wsdl is generated.
> A simple (if not very elegant) fix would be to simply remove the namespace before adding it to the list again. If it's not present, nothing happens; if it is, it's moved to the first slot:
> public void setDefaultNamespace(String namespace) {
> if (namespaceMappings == null)
> namespaceMappings = new ArrayList();
> namespaceMappings.remove(namespace);
> namespaceMappings.add(0, namespace);
> }
