Justin Ross updated PROTON-968:
-------------------------------
Fix Version/s: 0.12.0
> [proton-j] channel-max handling is broken
> -----------------------------------------
>
> Key: PROTON-968
> URL: https://issues.apache.org/jira/browse/PROTON-968
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-j
> Affects Versions: 0.10
> Reporter: Robbie Gemmell
> Fix For: 0.12.0
>
>
> The channel-max handling in proton-j is broken.
> Transport[Impl] defines get/setChannelMax methods, which allow controlling
> the value sent in the Open frame emmitted for the connection. It defaults to
> the maximum 65535.
> The ConnectionImpl object has a getMaxChannels method that returns a hard
> coded value of 65535, and it is this limit value that is used by
> TransportImpl when selecting local channel numbers for sending Begin frame
> for new sessions. As such, it pays no notice of the limit value it announced
> in its Open frame, which may have been lower if configured on the transport.
> The remote channel-max receiver from the peer isn't used at all other than
> for return via getRemoteChannelMax(). The above process will similarly pay it
> no attention to it when selecting channel numbers for new sessions and so may
> select a channel number above the remote peers limit [and perhaps also its
> own, again].
