Is this expected to run successfully? I am seeing failures when running with `wstest -m fuzzingserver`. For example in 9.1.3, when the test client tries to send the message back, the fuzz server closes the connection with status 1007 and reason "encountered invalid UTF-8 while processing text message at payload octet index 229230".
Furthermore, this results in exceptions on the client side that obscure the actual server error: SEVERE: Failed to send close message to remote endpoint java.io.IOException: java.util.concurrent.ExecutionException: java.io.IOException: Broken pipe at org.apache.tomcat.websocket.WsRemoteEndpointImplBase.startMessageBlock(WsRemoteEndpointImplBase.java:203) at org.apache.tomcat.websocket.WsSession.sendCloseMessage(WsSession.java:408) at org.apache.tomcat.websocket.WsSession.close(WsSession.java:353) at org.apache.tomcat.websocket.WsFrameClient.close(WsFrameClient.java:81) at org.apache.tomcat.websocket.WsFrameClient.access$2(WsFrameClient.java:71) at org.apache.tomcat.websocket.WsFrameClient$WsFrameClientCompletionHandler.failed(WsFrameClient.java:110) at org.apache.tomcat.websocket.WsFrameClient$WsFrameClientCompletionHandler.failed(WsFrameClient.java:1) at sun.nio.ch.Invoker.invokeUnchecked(Invoker.java:128) ...
