Description

The changes made by QPID-7514 inadvertently opened the possibility that a browser may receive a deleted message. Internally, for queue browser, the queue entries are not acquired. Instead, a message reference is taken. It is the responsibility of the consumer target to release the message reference.

A coding error in AbstractQueue#attemptDelivery meant that the message reference was immediately released.

This defect never formed part of a release.
