Hi all I'm using a plain install of 1.4.0 and the node client "mqtt.js"
I noticed that when a client fails a login I get 12:27:24,921 WARNING [io.netty.channel.DefaultChannelPipeline] An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.: io.netty.handler.codec.DecoderException: java.lang.NullPointerException at io.netty.handler.codec.ByteToMessageDecoder.callDecode(ByteToMessageDecoder.java:442) Looking at the source the issue relies on the fact that the library send a different set of bytes (MQTT starts at array[5]) https://github.com/apache/activemq-artemis/blob/master/artemis-protocols/artemis-mqtt-protocol/src/main/java/org/apache/activemq/artemis/core/protocol/mqtt/MQTTProtocolManager.java#L131 I tried to handle the different position of protocol name in isProtocol and the exception is not thrown anymore Should I open an issue for that? Thank you Regards Luca
