                 Key: MUSE-283
                 URL: https://issues.apache.org/jira/browse/MUSE-283
             Project: Muse

          Components: WSN NotificationProducer
    Affects Versions: 2.2.0
         Environment: os: unix on solaris 
            Reporter: Asaf Zafran

            Priority: Critical


we have extended the SimpleNotificationProducer.
in the method 
public void publish(QName topicName, Element[] content, EndpointReference consumer) throws
SoapFault

we have called the method:
Iterator i = getSubsriptions().iterator();

and the line 
iterator.next();
has caused a ConcurrentModificationException.
the stack trace is :
