RFR [13] 8217429: WebSocket over authenticating proxy fails to send Upgrade headers

[Pavel Rappo]

Chris, thanks for doing this! I have two questions on this change.

1. After this change has been applied, there will be a circular dependency
between HttpRequestImpl and OpeningHandshake. If this code is used by these two
classes maybe we are better off extracting it into some (already existing) third
class?

2. Why does this change add server.close() to each and every test method of
WebSocketTest? If I'm not mistaken that's what @AfterTest public void cleanup()
is supposed to do.
