OverlappingUnicastMergeTest fails to receive all messages

OverlappingUnicastMergeTest does the following:

• set up three channels a,b,c with the layers MERGE2, VERIFY_SUSPECT and FC removed
• the receiver of each channel will look at all incoming messages: if mcast, ignore it; if unicast, add to the list of messages received
• inject some new view into the channels which represents a view configuration which should be recovered from
• send messages to the channels and check that the messages are received, despite the injected view

OverlappingUnicastMergeTest this test is failing in a number of ways (i.e. many of the test methods are failing within the test class on multiple platforms.

What we expect to see is:

receiver A: ucasts=15
receiver B: ucasts=15
receiver C: ucasts=15

What we instead see is:

receiver A: ucasts=15
receiver B: ucasts=11

ucasts for B: 
B: unicast msg #1 from B B: unicast msg #2 from B B: unicast msg #3 from B B: unicast msg #4 from B B: unicast msg #5 from B  A: unicast msg #1 from A C: unicast msg #2 from C C: unicast msg #3 from C A: unicast msg #4 from A C: unicast msg #4 from C C: unicast msg #5 from C 

The order here is the order in which the unicasts were received from all three senders by the single receiver. For example, in the above, in testWithViewBC, channel A should receive messages #1 through #5 from channels A, B and C, but it does not receive #1 from channel C.
