Re: SASL problem with 3.4.4 Java client
How about if we revert
https://issues.apache.org/jira/browse/ZOOKEEPER-1437 and cut 3.4.5 RC0
today? Robert, Julio, et. al. could help verify the "fix". We can
re-introduce 1437 in 3.4.6 and significantly reduce the risk until
that's had more time to bake (say cut 3.4.6 a few months down the
line).
