>             Fix For:
> Found a few cases in the AMQP handlers where proton objects are used outside the connection
lock where the usage can cause updates to the Transport work list which if happens concurrently
can break the state of the work list.  
> Also found one case where a the code if offering credit to a sender which is not necessary
as the sender credit is determined by the remote receiver flowing credit to it.
