> I've seen this exception occurring from time to time in the BDB HA test
> MultiNodeTest#testInFlightTransactionsWhilstMajorityIsLost
> It seems that NPE occurs on heavy loads when multiple connections are trying
> to restore connectivity because of failover. The issue might affect users
> severely production deployments of the 6.x brokers, as NPE kills the broker
> and manual intervention could be required to start-up the broker
