When should we close the handlers in CXF?

[Unreal Jiang]

Hi guy,
  In JAX-WS spec, it describe that A handler’s close method is called at the 
conclusion of a message exchange pattern (MEP). 
  How can we apprehend it? Does it mean that we should close handlers when the 
response is returned to client?
  
  
  But in sun's ri, it close handlers at handlers process finished such as  
outband & inbound handler chain finished at both client and server  side, so 
there have four times close in a request-response MEP. 
  
  Do you guys have any idea about Which approach is conform to spec? 
  
  
  Any comment will be appreciated.
  
  Cheers
  Unreal
