Posted by Martin Ritchie <ri...@apache.org>.
There is a comment on the JIRA with a description of what the
resolution was. Do you want more details?
Martin Ritchie [27/Sep/06 04:40 AM]
Revision 450401.
While the data was being put in tot the unack'd map correctly the sync
block did not include the writeFrame call hence the messages could be
sent to client out of order.
This revision should finally resolve this issue.

Can you add a wee note saying roughly how it was fixed?
