> DEBUG 05-01 16:10:21.741 o.a.w.p.w.j.WicketEndpoint:82 [EventExec-e2-t9] -
> Web Socket connection with id '10' has been closed with code '1006' and
> reason: Broken pipe
> {code}
> Here are some more details on this issue
> In our code I'm using IWebSocketConnection.sendMessage(String) method
> The call is wrapped with try/catch to correctly handle any exception [1]
> The problem is hard to reproduce due to IOException should happen exactly at
> time of sendMessage do it's job
> (in original report author hammer the page with F5 until error will occur)
> As a result my try/catch doesn't play, I got "zombie" IWebSocketConnection in
> IWebSocketConnectionRegistry
> and incorrect application state due to I'm expecting to get disconnect from
> onError/onAbort of my WebSocketBehavior
> [1]
