RFR 8245245 : WebSocket can loose the URL encoding of URI query parameters

[Rahul Yadav]

Hello,

Request to have my fix reviewed for issue:

JDK-8247675 :  WebSocket can loose the URL encoding of URI query parameters

The fix updates the jdk.internal.net.http.websocket.OpeningHandshake
to ensure that the URL is not reencoded/decoded and loose the original
encoding
