That did the trick. By converting the sample code to Java I was able to see what it was doing.
It was defining the message variable as javax.jms.Message which doesn't have the correct methods. When I explicitly defined/cast the message as ActiveMQBytesMessage then it worked.

Do you see the expected methods? What JavaDocs are you looking at for reference? FWIW, the code for the 5.7.0 version of ActiveMQBytesMessage is here [1].
