OneWay Destination / Original Thread / Exception

[Coder One]

With CXF 2.2.5, my custom Destination makes use of the USE_ORIGINAL_THREAD 
setting

@Oneway
void f()
{
   throw new RuntimeException("ERROR");
}

incomingObserver.onMessage(cxincomingmsg);
Exception e = (Exception)cxincomingmsg.getContent(Exception.class);

e is always null.  How can I retrieve the exception in my custom destination 
when the function is @Oneway and throws an exception?

Thank-you!
