My guess is there's something changed with the websocket support? at org.apache.wicket.request.cycle.RequestCycle.processRequestAndDetach(RequestCycle.java:297) ~[wicket-core-7.3.0.jar:7.3.0] at org.apache.wicket.protocol.ws.api.AbstractWebSocketProcessor.broadcastMessage(AbstractWebSocketProcessor.java:257) ~[wicket-native-websocket-core-7.3.0.jar:7.3.0] at org.apache.wicket.protocol.ws.api.AbstractWebSocketProcessor.onClose(AbstractWebSocketProcessor.java:182) ~[wicket-native-websocket-core-7.3.0.jar:7.3.0] at org.apache.wicket.protocol.ws.javax.WicketEndpoint.onClose(WicketEndpoint.java:71) ~[wicket-native-websocket-javax-7.3.0.jar:7.3.0]
