    With pattern 'Scatter-Gather', if an error or a fault is returned by a service provider consumed, a response can be directly returned and interrupting the pattern process. In this case it is not needed to invoked service providers not already invoked. Service providers consumed must be invoked only if the current pattern process instance is not terminated.

    Otherwise, the following error occurs because the incoming message was returned and the component does not own it:

    java.lang.IllegalStateException: The component does not owns the MessageExchange
	at org.ow2.petals.jbi.messaging.exchange.MessageExchangeWrapper.checkComponentOwnsExchange(MessageExchangeWrapper.java:282)
	at org.ow2.petals.jbi.messaging.exchange.MessageExchangeWrapper.getRole(MessageExchangeWrapper.java:161)
