/**
 * SPI interface to be implemented by components that manage
 * JMS ServerSessions. Usually, but not necessarily, an implementation
 * of this interface will hold a pool of ServerSessions.
 *
 * <p>The passed-in ListenerSessionManager has to be used for creating
 * and executing JMS Sessions. This session manager is responsible for
 * registering a MessageListener with all Sessions that it creates.
 * Consequently, the ServerSessionFactory implementation has to
 * concentrate on the actual lifecycle (e.g. pooling) of JMS Sessions,
 * but is not concerned about Session creation or execution.
