Description

I'm facing this issue intermittently in both Karaf 4.1.7 and latest Karaf 4.2.6.

karaf@root()> Exception in thread "JMX Connector Thread [service:jmx:rmi://127.0.0.1:44444/jndi/rmi://127.0.0.1:1099/karaf-root]" java.lang.RuntimeException: Could not start JMX connector server

I've traced the code and found something in 

org.apache.aries.jndi.ContextHelper.getInitialContext(BundleContext, Hashtable<?, ?>) (org.apache.aries.jndi.core-1.0.2)

 

ContextProvider provider = getContextProvider(context, environment);

 if (provider != null) {
 return new DelegateContext(context, provider);
 } else {
 String contextFactoryClass = (String) environment.get(Context.INITIAL_CONTEXT_FACTORY);
 if (contextFactoryClass == null) {
 return new DelegateContext(context, environment);
 } else {
 throw new NoInitialContextException(Utils.MESSAGES.getMessage("no.initial.context.factory", contextFactoryClass));
 }
 }

there the provider = null and it's creating DelegateContext without initial context.
The provider should be retrieved from

ServiceReference[] references = AccessController.doPrivileged(new PrivilegedAction<ServiceReference[]>() {
 public ServiceReference[] run() {
 return Activator.getInitialContextFactoryServices();
 }
 });

But getInitialContextFactoryServices is returning nothing, maybe the service is not up yet.
