Description

The subj method has restrictions on the types of objects it can accept, but those restrictions aren't implemented. Testcase below.

// get a live session
        ConnectionFactory cf = new ActiveMQConnectionFactory("vm://localhost?broker.persistent=false&broker.useJmx=false");
        Session session = cf.createConnection().createSession(false, Session.AUTO_ACKNOWLEDGE);

        StreamMessage sm = session.createStreamMessage();

        // only primitives (with wrappers), String and byte[] are allowed:
        // http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/jms/StreamMessage.html#writeObject(java.lang.Object)

        try
        {
            sm.writeObject(new Object());
            fail("Should've failed with MessageFormatException");
        }
        catch (MessageFormatException e)
        {
            // JMS 1.1 spec, Section 7.3 Standard Exceptions, page 89, 1st paragraph
            // expected
        }
