This workaround is introduced at ZOOKEEPER-784. And after 3.4.0 both the server & the client handle readOnly field.
However, as jute's serialize & deserialize implemented atomically (no optional field I think?), this PR should logically break client version less than 3.4 as documented here. I'll give it a test and wonder what the version policy and compatibility promise we should keep.

Confirm work start from 3.4.0, not for 3.3.6 and before.
