Work Description: orpiske commented on issue #2564: ARTEMIS-2183 Useless
statement in public synchronized List
URL: https://github.com/apache/activemq-artemis/pull/2564#issuecomment-466762846
> I would assume this is a bug and actually is meant to be populated by an
internal field
Maybe it should be combining either refsToAck or pagedMessagesToPostACK ...
or, maybe, even both?

> The method returns empty list, which may be wrong (looking at the method
> name). There is absolutely nothing gained by adding content of empty inst
> into itself, as in {{listRet.addAll(listRet)}}.
> Doing the addAll thing can be an error under ErrorProne compiler.
