BAM Support in Camel - ActivityMonitorEngine-- Failed to process expiration of: ActivityState[19 on ProcessInstance[44] Activity[1 name: bamB]]. Reason: java.lang.NullPointerException

[Ravi Gupta 7]

I have created two activeMQ [bamA and bamB].
Also created a AcctInqProfileCheckActivity as a routeBuilder under camel 
context.
Below is the overridden configure () method. 

When I send a message to bamA using ActiveMQ then it is giving me below error. 
I am sending message to bam2 after 3 seconds too.
