Hi,

I'm seeing the below exception when trying out the esb sample 272 at [1].

[2017-04-04 18:13:31,202] ERROR - AsyncCallback *ClientId longer than 23
characters*
java.lang.IllegalArgumentException: ClientId longer than 23 characters

I have tried:

   - Change the org.eclipse.paho.client.mqttv3-1.1.0.jar
   to org.eclipse.paho.client.mqttv3-1.1.1.jar
   - Tried with both WSO2 Mb and mosquitto broker

Still got the same error when sending message in the out sequence.

​Thanks.
