Tomas Forsman commented on AXIS2-5329:
--------------------------------------
I do no longer believe that just making the "updated" method synchronized is
the correct solution. After reviewing the code a bit more I believe it has
other issues..
>From the method OSGiConfigurationContextFactory.updated(Dictionary dictionary)
Registry servicesRegistry = new ServiceRegistry(context,
configCtx);
Registry moduleRegistry = new ModuleRegistry(context,
configCtx, servicesRegistry);
bundleTracker.addRegistry(servicesRegistry);
bundleTracker.addRegistry(moduleRegistry);
bundleTracker.open();
I believe this means that if the configuration for the axis2 bundle is updated,
the BundleTracker will get more and more Registy registered.. also the
"updated" method registers services every time it is run.. possible that the
OSGi container fix this under the hood, but i'm not sure.
