Unclear What triggers holding versus releasing acks, and what problem the batching solves, is not stated.
What
Two new methods, holdProcessedAcks and releaseProcessedAcks, were added to a session/transport object. holdProcessedAcks starts buffering delivery acknowledgements instead of sending them immediately, and releaseProcessedAcks flushes any buffered acknowledgements out as 'processed' delivery reports.
Why
This allows delivery acknowledgements to be batched and released together rather than sent one at a time, which the finding does not further explain the purpose of.
