Bela Ban updated JGRP-751:
--------------------------
Fix Version/s: 2.6.3
2.7
Description:
ReplicatedHashMap does not correctly handle state transfer
during a merge, leaving members with inconsistent map
entries.
Specifically, on receipt of a MergeView no attempt is made
to reconcile the state of all members. Each member retains
the entries it had while partitioned, though all members
will correctly apply subsequent mutations.
I've attached a unit test that demonstrates the bug and also
a patch that corrects the behavior (specifically, by calling
getState() on the coordinator of each subview on receipt of
a MergeView).
