Camel route received exchange body as null, while consuming file from JMS.

Issue

• How to receive or interpret a file from JMS, Using Camel?
• In the apache camel documentation, it said that if a File is send a to a JMS queue, Camel convert the file into a ByteMessage, and the consumer will expect a byte[] data type to start its route. It's that correct?
• When performed testing, expecting byte[] data type from the consumer route instead a file, and the exchange body comes null.
