I would make this method static and uses `(pointer & 0xFFFF_FFFFL) << 32`
to make explicit what is happing during the upcast
> JMS MessageProducer fails to expose exception on send when message is sent

> Key: ARTEMIS-1545
> URL: https://issues.apache.org/jira/browse/ARTEMIS-1545
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Reporter: Michael Andre Pearce
>
> When sending persistent, behaviour is blocking and a Security exception is
> thrown. The same behaviour that the client is exposed to the client when
> sending non-persistent, so that a client could log or take action
> asynchronously.
> This can be recreated easily by the following:
> Add the following security section , that means guest is not auth'd to send
> to "guest.cannot.send"
> activemq-artemis/tests/jms-tests/src/test/resources/broker.xml
> <security-setting match="guest.cannot.send">
> <permission type="createDurableQueue" roles="guest,def"/>
> <permission type="deleteDurableQueue" roles="guest,def"/>
> <permission type="createNonDurableQueue" roles="guest,def"/>
> <permission type="deleteNonDurableQueue" roles="guest,def"/>
> <permission type="consume" roles="guest,def"/>
> <permission type="browse" roles="guest,def"/>
> <permission type="send" roles="def"/>
> </security-setting>
> Then add the following tests to this test (first is proving exception
> correctly is thrown when persistent is sent using jms api, and second shows
> behaviour difference and no error):
> activemq-artemis/tests/jms-tests/src/test/java/org/apache/activemq/artemis/jms/tests/SecurityTest.java
> /**
> * Login with valid user and password
> * But try send to address not authorised - Persistent
> * Should not allow and should throw exception
> */
> @Test
> public void testLoginValidUserAndPasswordButNotAuthorisedToSend() throws
> Exception {
> ConnectionFactory connectionFactory = new
> ActiveMQConnectionFactory("tcp://localhost:61616");
> Connection connection = connectionFactory.createConnection("guest",
> "guest");
> Session session = connection.createSession();
> Destination destination = session.createQueue("guest.cannot.send");
> MessageProducer messageProducer = session.createProducer(destination);
> try {
> messageProducer.send(session.createTextMessage("hello"));
