Hello,
I have a jar file created with b4j to connect to a remote server via websocket and get live updates of a price of stg. My jar randomlu crashes with this :
I assume , websocket connection is being broken but I have a connect method under ws_closed so there shouldnt be a problem. Also I have a heartbeat sender with timer so what may cause the error ?
