> I get a NamingException with the following bundle activator if aries-jndi is
> present (I tried the current 0.4-SNAPSOT and 0.3):
> public class Activator implements BundleActivator {
> @Override
> public void start(BundleContext bundleContext) throws Exception {
> Map<String, Object> env = new HashMap<String, Object>();
> env.put("osgi.service.jndi.bundleContext", bundleContext);
> JMXConnectorFactory.connect(new
> JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:1717/jmxrmi"), env);
> }
> @Override
> public void stop(BundleContext arg0) throws Exception {
> }
> }
> The bundle context in the environment is necessary to work around another
> issue.
> The NamingException is thrown by
> com.sun.jndi.url.rmi.rmiURLContextFactory.getObjectInstance() if the first
> parameter is not an URL. This method is called from
> org.apache.aries.jndi.ObjectFactoryHelper.getObjectInstanceUsingObjectFactories().
> This method iterates over all registered ObjectFactories to check if there
> is a better implementation than the one provided in the first argument,
> however if it comes to Sun's object factory the NamingException occurs (and
> will be propagated upwards) even though the proxy object that is already
> there is actually fine.
> Therefore I would propose the following change:
> Index: src/main/java/org/apache/aries/jndi/ObjectFactoryHelper.java

> The empty catch block is needed because obviously some ObjectFactories throw
> a NamingException instead of returning null in some circumstances.
