Subject: QPID-2928 QPID-2737 The isExclusive method in
 BasicMessageConsumer_0_10.java takes the dest syntax into consideration when
 determining the exclusivity for a subscription. For destinations created
 using the addressing syntax, Queue subscriptions are non exclusive by default
 but are allowed to change it. Topic subscriptions are exclusive and is not
 allowed to change the value.
