Some more comments on this: The current default for for JG 2.6.3 and the proposed default for JG 2.4.3 is auto_reconnect=true and auto_getstate=false. If you have channel that uses state transfer and accepts those defaults, if the channel gets shunned and reconnects, a state transfer will not happen after the reconnect. As a result, the app's state on that node will be out of sync with the rest of the cluster. Probably not a good thing. Recommend JBM never just accept the defaults. Always specifically configure what you want via channel.setOpt(...). If you guys are doing a CP release for EAP 4.3 CP01 and can add that in, then you are set no matter what the defaults are in a particular JGroups release.
