Robbie Gemmell resolved PROTON-853. ----------------------------------- Resolution: Fixed Fix Version/s: 0.9.1 > [proton-j] the transport emitted a new attach frame for a link in the process > of being closed > --------------------------------------------------------------------------------------------- > > Key: PROTON-853 > URL: https://issues.apache.org/jira/browse/PROTON-853 > Project: Qpid Proton > Issue Type: Bug > Components: proton-j > Affects Versions: 0.9 > Reporter: Robbie Gemmell > Assignee: Robbie Gemmell > Fix For: 0.9.1, 0.10 > > > When upgrading to use 0.9 for the JMS client, we see some NPEs on the client > as it tries processing the events being emitted by the connection. This was > due to multiple link attach and detach frames arriving in the for the same > consumer link. > What appears to be happening is that while closing the consumer, after the > client emits its detach frame proton then emits a new attach frame for the > link, before the server responds to the original detach, even though the > client made no attempt to recreate the consumer. It looks like the clients > handling of a flow frame which arrived after it emitted the original detach > meant that the link was modified, and the transport reacted by sending out a > new attach. This appears to be due to a change made in 0.9 for PROTON-154. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
