In respect that we remove `JMSSerializationUtils::hasJMSNativeSupport` Is
this still relevant for us?
> Serializable attributes are not preserved by enqueue/dequeue on a JMS queue
> ---------------------------------------------------------------------------
>
> Key: JAMES-2167
> URL: https://issues.apache.org/jira/browse/JAMES-2167
> Project: James Server
> Issue Type: Bug
> Components: Queue
> Affects Versions: master
> Reporter: Tellier Benoit
> Priority: Major
>
> A call to toString breaks convertion for generic serializable attributes.
> The dequeued email will have only a toString version of it. We are expecting
> the exact same value, just deserialized.
> We should ensure the value of Serializable attributes gets preserved by
> enqueue/dequeue operations. We should add a unit test for this, and fix it.
