Raised when an attempt is made to subscribe a listener to
a topic, but listener does not satisfy the topic's message data
specification (MDS). This specification is inferred from the first
listener subscribed to a topic, or from an imported topic tree
specification (see pub.addTopicDefnProvider()).
