> 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.
