Web Socket Error on AmazonEchoControl binding every 65 seconds

Add-ons Bindings
55

I think it is only necessary to add an amazon account to the binding and the issue appears.
You should take a look at:

org.openhab.binding.amazonechocontrol.internal.WebSocketConnection

The method:

initPongTimeoutTimer()

starts the timer to close the webSocketClient through the method:

close()

in the same class.
