Normally, that would be the case.   Thus, for normal two way ops, it should be 
OK.   I'd work on getting the normal cases working first and then we can 
figure out what to do about the others.  (On trunk, there IS  a flag that can 
set the endpoint to use the same thread for the one ways as well.   Not in a 
released version yet though)

Well, I don't think JAX-RS would ever use the workqueue anyway.  They don't 
have one-way ops.   Thus, it may not be an issue for you.


Actually, your last note to me made me think of something else that could be 
problematic.   For attachments (and message logging), we use a special output 
stream that once a threshold is reached (64K by default), it starts saving to 
temporary files on the file system.   There is a system property (and I think 
a config setting) to control that.   However, it would probably be good to 
update the code and if "new FileOutputStream(...)" fails (or createTempFile or 
whatever), it would just proceed keeping it in memory.   Patches would be 
welcome.   :-)
