@clebertsuconic Do you know of any other way (faster) to know if a

> Project: ActiveMQ Artemis
> Issue Type: Improvement
> Components: Broker
> Reporter: Francesco Nigro
> Assignee: Francesco Nigro
> Priority: Minor
>
> CoreMessage::checkProperties perform too many volatile read/write and has a
> too big body just to handle exceptional cases, while
> cleanupInternalProperties is called on the hot path of session send, but is
> performing too many synchronized operations and loopup on TypedProperties.
