Issue

Within a Camel route (written in blueprint) a thread element is used to control the number of simultaneous executions of a block of actions.
Property rejectedPolicy="Abort" is set, as requirement is to capture when a task is rejected and respond to the consumer in an appropriate manner.
However when Abort reject policy exception is thrown, following is the exception trace

org.apache.camel.CamelExecutionException, 
caused by Caused by: java.util.concurrent.RejectedExecutionException,

Above exception is not caught by camel-route. It is propogated back to the consumer.
Consequently cannot respond to the consumer in an appropriate manner.
