org.springframework.web.socket.sockjs.SockJsTransportFailureException
Indicates a serious failure that occurred in the SockJS implementation as opposed to in user code (e.g. IOException while writing to the response). When this exception is raised, the SockJS session is typically closed. @author Rossen Stoyanchev @since 4.0
