------------------------------------
Summary: [Broker-J] refusing-attach while rejecting consumer does
not set required initial-delivery-count field
Key: QPID-8523
URL: https://issues.apache.org/jira/browse/QPID-8523
Project: Qpid
Issue Type: Bug
Components: Broker-J
Affects Versions: qpid-java-broker-8.0.4
Reporter: Robbie Gemmell
Attempting to create a consumer link from e.g. a non-existing address results
in refusal of the link, which in case of a consumer is done by sending a
'response' attach with null source to indicate the terminus wasnt created,
followed by a detach with the error.
The broker does send an attach without a source, but it omits the
initialDeliveryCount value from the attach, which the spec says is required
when role=SENDER ("This MUST NOT be null if role is sender, and it is ignored
if the role is receiver."). Protocol libraries validating such required values
will run afoul of this, leading to decode error that can bring the connection
down unnecessarily.
>From looking at the wire encoding, it appears only the first 3 fields (name,
>handle, role) of the attach are being set, with the rest unpopulated and thus
>being equivalent to null or any default they may have.
