When standalone JMS client is trying to create connection to server in cluster then gets java.lang.NullPointerException - see attached log.

Test scenario:
1. Start EAP servers A and B in cluster - collocated topology
2. Deploy durable queue 'testQueue'
3. Try to send messages to queue 'testQueue'

In step 3. client gets java.lang.NullPointerException during connectionFactory.createConnection(). It seems that attribute mapBackof is null when calling Topology.addMember(...) -> mapBackof.get(nodeId);

I've attached configuration for node A and B (just copy to appropriate directory in EAP distribution). Please let me know if there is something more you need.

Thank you,

Mirek
