RFR JDK-8027308: HttpURLConnection should better handle URLs with literal IPv6 addresses

[Pavel Rappo]

Hi everyone,

Could you please review my change for JDK-8027308?

http://cr.openjdk.java.net/~prappo/8027308/webrev.00/

The issue in question actually consists of 2 issues. The first one is about supporting zone id syntax in URIs. Which is described in [1]. The second one is about handling link-local addresses in HTTP headers. The current status of [1] is "Proposed Standard". I wasn't able to use the described syntax even with the system utils locally (OS X 10.9.3). So I think the work on the first issue can be postponed until [1] is widely implemented.
The use case in the second issue can be easily addressed. The only thing is that given the complexity of interaction between HttpURLConnection and different authentication schemes the change won't fix the scenario of proxied http connection. This is something that should be done after the refactoring of sun.net.www.protocol.http.
