RFR: 8263442: Potential bug in jdk.internal.net.http.common.Utils.CONTEXT_RESTRICTED

[Michael McMahon]

Hi,

The fix for the reported bug in Utils.CONTEXT_RESTRICTED caused a couple of regression failures, which turned out to be another bug exposed by this fix where HTTP/1.1 CONNECT requests with authentication were filtering out proxy authentication headers wrongly. This was because the HttpRequestImpl created for the repeated CONNECT was putting the system headers in the user headers area of the HttpRequestImpl. The fix for that is to supply the user and system headers direct to the place where the new HttpRequestImpl is created.

Thanks
Michael
