> Based on JGroups expert's advice, the way we detect if a member is the first member in the cluster is not correct. 
> From Vladimir's email:
> ...JBM code assumes that if getState returns false that the first member is starting - which is not true. It just indicated that state transfer was not successful (timeout/non-serializable state/first member in cluster).
> We shall make the correct changed as Vladimir suggested (he also provided a fix, see attachment).
