org.jboss.ws.core.soap.SOAPMessageImpl does not implement setProperty and getProperty methods

I am trying to implement SOAPClient that invokes WebService by use of Dispatch<Object> interface with JAXB.
When trying to write the code like in the following tutorial --> http://www.omii.ac.uk/wiki/JaxWsTutorial#section-JaxWsTutorial-Example6.JAXWSinvocationusingtheDispatchObjectinterfacewithJAXB
I got an exception as below:

13:55:58,453 ERROR [DispatchImpl] Cannot dispatch message
java.lang.UnsupportedOperationException: setProperty must be overridden by all subclasses of SOAPMessage

Looking into the source of the classes listed in stacktrace I found that SOAPMessageImpl class does not implement required setProperty() and getProperty() methods.
