Any pending work for any previous consumer, delivered put > back on the queue or pending transaction completion rollback or commit or > close must have occurred before dispatch to a new consumer resumes. > The removal of the consumer must wait to release the exclusive consumer flag. > To do this it must be able to be sure that all previous completions on the > context are done. > This requires consistent use of the operation context to enforce sequential > completion. > This problem was visible with openwire which typically has a large prefetch, > resulting in many messages in the delivering list, moved there on rollback > from the acks list of a transaction. -- This message was sent by Atlassian Jira (v8.20.10#820010)
