Clebert Suconic commented on ARTEMIS-3751:
------------------------------------------
The issue is that the message was not sent as Large Message from the client,
but it became large on the server's through protecting the journal-buffer-size.
the asLargeMessage on LargeServerMessageImpl was to protect such cases, but the
compressed large message was missed in there.
Nice catch.. I am merging the PR with a few adjustments.

> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: JMS
> Affects Versions: 2.18.0, 2.20.0
> Reporter: Alvin Kwekel

> Messages are cut off meaning that the message is only partially written to
> the broker. The messages are stored in incomplete form in the
> "large-messages" directory. No exception is thrown. Consumers inevitably
> also get the incomplete partial messages.
>
> To reproduce
> - Message size must exceed the minimal large message size
> - Message size must be less than twice the minimal large message size
> - Minimal large message size must be more than about 1MiB
> - Large message compression must be enabled
> - Message must be a JMS bytes message
> - If messages are smaller than the minimal large message size there is no
> issue
> - If messages are twice as big as the minimal large message size there is no
> issue
> - If the minimal large message size is less than about 1MiB there is no issue
> - If large messages are not compressed there is no issue
> - If the message is a text message there is no issue
> Tested with both Artemis client version 2.18.0 and 2.20.0 while my Artemis
> server is at 2.20.0
> I've created a project that reproduces the issues:
