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
onClose/onError/onAbort of my WebSocketBehavior
