Robert Dale commented on TINKERPOP-2262:
----------------------------------------
TP 3.3 uses Netty 4.0.x. Does the affects version still apply? I don't think
we would update 3.3 to use Netty 4.1.x otherwise we would have done that.
> Improve Netty protocol handling

> Key: TINKERPOP-2262
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2262
> Project: TinkerPop
> Issue Type: Improvement
> Components: driver, server
> Affects Versions: 3.3.7, 3.4.2
> Reporter: Divij Vaidya
> Priority: Major
>
> 4.1.37 adds [https://github.com/netty/netty/pull/9116] which is critical to
> the stability of the Java Client.
> After the upgrade a follow-up task would :
> 1. change the Java Client to set the newly introduced flag
> "closeOnProtocolViolation" to false. This would prevent causing all the other
> requests using the same channel to fail when a single request causes a
> protocol violation.
> 2. introduce the protocol exception error handling code on the client to
> handle protocol violation exceptions. Currently, the code force replaces the
> channel, thus closing all the other requests being served on the channel.[
