-------------------------------------------------------------------------
I believe this is due to an upgrade to ZK's Netty dependency, in 3.5 somewhere
between 3.5.7 (which is fine) and 3.5.8 (which triggers this problem). A
similar dependency upgrade happened in the 3.6 code line as well.
Edit: Perhaps the effective version of Netty is too old (relative to ZK's
version), leading to this issue, so managing up our version of Netty could
solve it.
