Keith Wall commented on PROTON-1077:
------------------------------------
Robbie, I repeated the test described by QPID-6863 against the Java Broker
with the above Proton change applied. I was no longer able to reproduce the
issue. I ran for fifteen minutes with no recurrence. We'll be looking at the
Java Broker issue (QPID-6947) separately.
> receiver link and transport view of credit can become disjoint when sending
> link sends flow frames

> Key: PROTON-1077
> URL: https://issues.apache.org/jira/browse/PROTON-1077
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-j
> Affects Versions: 0.11
> Reporter: Robbie Gemmell
>
> If a recieving link receives flow frames from the sending peer updating
> advancing the delivery count [and setting credit to 0], then recieves flow
> frames from the sender updating credit but not advancing the delivery count,
> then receives messages, the Link and TransportLink views of the credit can
> become disjoint, leading applications to think they have a different amount
> of credit than they actually do, and leading to a different amount of new
> credit being flowed to the sender than expected, even none.
