Robbie Gemmell created PROTON-940:

             Summary: provide the session initial incoming window via Begin 
rather than sending a separate Flow
                 Key: PROTON-940
             Project: Qpid Proton
          Issue Type: Bug
          Components: proton-j
    Affects Versions: 0.9.1, 0.9, 0.8
            Reporter: Robbie Gemmell
            Assignee: Robbie Gemmell
             Fix For: 0.10

When a session is created, a Begin frame is sent. One of the fields on the 
frame is the initial incoming window. Instead of populating the field, Proton-J 
currently sets it to 0 but then immediately discovers the window is 0 and sends 
a seperate Flow frame (in the same transport output sas the Begin frame) 
changing the window to the actual calculated value.

This result is equivalent in the end and allowed by the protocol, but is not 
particularly obvious behaviour and is different than proton-c. The initial 
incoming window value should be conveyed in the Begin frame instead, removing 
need for the immediate Flow.
