Subject [jira] Resolved: (CXF-3271) WS-RM code does not support InOrder assurances
Date Thu, 03 Feb 2011 21:34:31 GMT

Daniel Kulp resolved CXF-3271.
------------------------------

       Resolution: Fixed
    Fix Version/s: 2.3.3
         Assignee: Daniel Kulp


Patch applied.

I modified the patch so that if continuations are available, it will use them instead of blocking
on the thread.

One optimization that COULD be done is instead of wakeing up ALL the waiting continuations,
we could just fine the one for the next in the sequence (and duplicates) and wake them up.
 

Also, the Jetty continuations don't work with one-ways.  I'll need to figure out what to do
about that.  Not sure it really matters for most cases though.   The fallback to the wait()
method works fine.

> The WS-RM implementation does not support InOrder assurances. When InOrder is used alone
(which is effectively the same as combined with AtLeastOnce) or with AtMostOnce messages are
just delivered in whatever order they arrive. When InOrder is combined with ExactlyOnce the
code never delivers any messages (due to a logic error in DestinationSequence.allPredecessorsAcknowledged()).
See attached integration test and policy documents to demonstrate the issues.
