>             Project: Camel
>          Issue Type: Bug
>    Affects Versions: 2.18.0
>            Reporter: Rajithamol Lakshmanan

> I am using camel-aggregator for aggregating JMS messages. When I upgraded the camel version
from 2.15.6 to 2.18.0 I started getting ClassCastException  in the aggregatorstrategy class.

> Error occurred during aggregation. Exchange[]. Caused by: [java.lang.ClassCastException
- org.apache.camel.impl.DefaultMessage cannot be cast to org.apache.camel.component.jms.JmsMessage].

> I debugged and found that AggregatorProcessor calls ExchangeHelper.createCorrelatedCopy
which copies the exchange harcoding the safeMode to be true. 
> In 2.18.0 : Exchange copy = exchange.copy(true); 
> In 2.15.6 : Exchange copy = exchange.copy(); 
> Because of this we are not getting the original JMS message- javax.jms.Message inside
org.apache.camel.Message .
> Can we have an option to configure this deep copy option?
