> Prepare LengthFieldBasedFrameDecoder for Netty upgrade
> ------------------------------------------------------

> Key: FLINK-8759
> URL: https://issues.apache.org/jira/browse/FLINK-8759
> Project: Flink

> Components: Network
> Affects Versions: 1.5.0

> Fix For: 1.6.0

>
> For a bug in Netty's shutdown sequence and overall improvements in Netty, I'd
> like to bump the version (and stay within the 4.0 series for now). The
> problem we faced in the past should not be relevant for credit-based flow
> control anymore and can be worked around (for the fallback code path) by
> restoring {{LengthFieldBasedFrameDecoder}}'s old behaviour of copying
> contents to new buffers instead of slicing the existing one (please refer to
> FLINK-7428 for the inverse direction).
