--------------------------------------
Summary: Karaf 4.1.7 - Could not start JMX connector server due to
javax.naming.NoInitialContextException
Key: KARAF-6416
URL: https://issues.apache.org/jira/browse/KARAF-6416
Project: Karaf
Issue Type: Bug
Components: karaf
Affects Versions: 4.2.6, 4.1.7
Reporter: Anh Tuan Nguyen
I'm facing this issue intermittently in both Karaf 4.1.7 and latest Karaf 4.2.6.
{code:java}
karaf@root()> Exception in thread "JMX Connector Thread

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)
{code:java}
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));
}
}
{code}
there the provider = null and it's creating DelegateContext without initial
context.
The provider should be retrieved from
{code:java}
ServiceReference[] references = AccessController.doPrivileged(new
PrivilegedAction<ServiceReference[]>() {
public ServiceReference[] run() {
return Activator.getInitialContextFactoryServices();
}
});{code}
But getInitialContextFactoryServices is returning nothing, maybe the service is
not up yet.
