[Htmlunit-user] Help with UpgradeException

[Ian C. <ian...@gm...>]

I seem to get this exception fairly consistently on startup.  I'm using
htmlunit to tests a page that is delivered to the client, and the client then
connects to the server via a websocket.
But it's unclear what the root cause is, here is the full exception:
