Wildfly 10 JAX-WS attachements: MTOM threshold not working as expected (?)

I have a JAX-WS endpoint defined by annotation @MTOM

and setting a threshold as shown below. So I expect any attachments less than 5MB to be sent in-line as base64binary

. But the answer to the soap always comes back as MTOM

for even small files.

Is this the expected behavior? How can I apply this flexibility otherwise?

@HandlerChain(file="/handler-chain.xml")
@MTOM(threshold=5242880) // 5MB limit for inline soap attachements else MTOM
public class WSImpl {

      

        
        
        
      

    

I'm interested in this behavior . It's not a specification, but at least the Metro

implementation behaves like (at least the old version) in jboss 5. Apache CXF

always dispatches as MTOM

if enabled and doesn't care about the threshold.
