> In a test that turns off use of TCP/IP stream sockets for cache
> communications (disable-tcp==true) it is possible for a member to be added as
> a "surprise member" even though it is already in the membership view. This
> is due to our UDP messages not including the member's "name" in the sender ID
> included in the message and that InternalDistributedMember.compareTo() uses
> the member name in comparisons. It doesn't really need to do that for
> partial IDs like these.
