Description

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);
}
