/**
 * This implementation supports Spring's extended "maxConcurrency"
 * and "prefetchSize" settings through detecting corresponding
 * ActivationSpec properties: "maxSessions"/"maxNumberOfWorks" and
 * "maxMessagesPerSessions"/"maxMessages", respectively
 * (following ActiveMQ's and JORAM's naming conventions).
