> 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).
