Review Comment:
the codec, apparently support a encoder value type that is empty. basically
you can add EncodingCodes.NULL on the encoding and you get an empty
ApplicationProperties.
I don't find it very useful but I see it on the codec.
As for the empty application properties I added a test.

> Key: ARTEMIS-5573
> URL: https://issues.apache.org/jira/browse/ARTEMIS-5573
> Project: Artemis
> Issue Type: Improvement
> Components: AMQP
> Affects Versions: 2.41.0
> Reporter: Clebert Suconic
> Assignee: Clebert Suconic
> Priority: Major
> Labels: pull-request-available
> Time Spent: 7h
> Remaining Estimate: 0h

> I have had a lot of issues, even recently on races between re-evaluating a
> message size in AMQP.
> Say a lazy decode happens at the wrong time and the memory estimates can be
> wrong.
> We have fixed issues along the years, but this is still a fragile process
> that is bound to fail. If an user for instance add a plugin breaking the
> chain of events.
> For that reason the memory estimate should already include enough estimation
> for any properties decoded and the process should be simplified.
> Less moving parts would mean less possibilities for bugs.
