+/**
+ * This class has not kept up to date with the topic_listener in the cpp tests. It should provide identical behaviour for
+ * cross testing the java and cpp clients.
+ *
+ * <p/>How the cpp topic_publisher operates:
+ * It publishes text messages to the default topic exchange, on virtual host "/test", on the topic "topic_control", for
+ * the specified number of test messages to be sent.
+ * It publishes a report request message (on same topic), with the header text field "TYPE", value "REPORT_REQUEST",
+ * optionally within a transaction, and waits for the specified number of consumers to reply to this request. The
+ * listeners should reply to this message on a queue named "response", on virtual host "/test", with some sort of message
+ * about the number of messages received and how long it took, although the publisher never looks at the message content.
+ * The publisher then send a message (on the same topic), with the header text field "TYPE", value "TERMINATION_REQUEST",
+ * which the listener should close its connection and terminate upon receipt of.
+ *
+ * @todo I've added lots of field table types in the report message, just to check if the other end can decode them
+ *       correctly. Not really the right place to test this, so remove them from
+ *       {@link #createReportResponseMessage(String)} once a better test exists.
