HandlerProvider is now an interface that can be used to plug in WebSocket handlers with per-connection scope semantics. There are two implementations, of the interface, one simple and a second that creates handler instances through AutowireCapableBeanFactory. HandlerProvider also provides a destroy method that is used to apply a destroy callback whenever a client connection closes.pull/292/head
