Description

The event admin handler should do a better job in reporting error. Especially the following subscriber (missing the data_key attribute):
@Subscriber(name = "tdmEventSubscriber-1", topics = "tdmEventTopic", data_type = "java.lang.String")
public void receive(String msg)

{ System.out.println("[DATA RECEIVER] Receive event on tdmEventTopic : " + msg); }

will throw this exception:
-> [ERROR] de.akquinet.gomobile.ea.test.SubscriberTest : Cannot find callback method receive(org.osgi.service.event.Event)
[ERROR] IPOJO-Extender : An error occurs when analyzing the content or starting the management of 17
java.lang.IllegalStateException: Cannot find callback method receive(org.osgi.service.event.Event)

The handler has detected a problem but try to use a wrong method (receiver(Event) instead of reporting the bad configuration and rejecting it.
