Hi Martyn, I just tried that: I upgraded the artemis-implementation in Wildfly-10 to 1.5.5 (I took the artemis-module as it is packaged in wilfdly-11-RC1. I also had to upgrade netty.io to 4.1.19 instead of 4.0.33 to make it work) I hit the exact same error: /Sep:13,15:55:11,656 WARNING (:Thread-2 (activemq-netty-threads):) [io.netty.channel.DefaultChannelPipeline] An exceptionCaught() event was fired, and it reached at the tail of the pipeline.
