This is because sendClose() in Java11WebSocket.disconnect() throws, potentially because the output stream is already closed. We previously would feed the exception into the onWebSocketFailure(Exception) machinery, which would then again attempt a disconnect. Since a failed sendClose() is nothing that needs special handling, we simply log the exception as error. Furthermore, we only issue sendClose() if the WebSocket's output is still open, i.e., if there is a chance that it actually works.
