Note that if you @Inject JMSProducer into a @ApplicationScoped bean then that's the scoping used, although it's not correct as the scope should be either @Request or @TransactionScoped

Why do you say that the "JMSContext ends up being potentially shared between multiple threads"?

The scope of the injected JMSContext is defined in the JMS 2.0 spec, section 12.4.4. "Scope of injected JMSContext
objects". Essentially, if there's a transaction in progress then the injected JMSContext will have transaction scope,
otherwise it will have request scope.

It looks like you're in a servlet here, and you haven't started a transaction, so the injected JMSContext must have
request scope.
