> Bug we encountered: using BlobMessage (FTP backend) and individual
> acknowledge, URL of BlobTransferPolicy was shared among messages following
> the acknowledge of messages.
> Example: 1 queue, 1 consumer, 1 producer, prefetch limit 5 messages
> - Producer generated 10 messages
> - Consumer received and processed (but do not ack) 5 messages
> - Consumer acked the 5 messages in a row
> - Consumer received 5 more messages and the first one shared the same
> BlobTransferPolicy and FTP URL that the last acknowledged messages.
> We tested the attached (one line) patch in our production server for more
> than one month and it did not the show the bug or any new one.
