[8u] RFR: 8183369: RFC unconformity of HttpURLConnection with proxy

[Jonathan Dowland]

Hello,

Please consider the this fix for jdk8u, for parity with Oracle 8u311.

** Note that it depends upon the backport of JDK-8161016 first, which is
   marked jdk8u-fix-request. **

The original patch applied clean after two unshuffles, but the test
required an edit to function properly in jdk8u, due to changes around
logging in jigsaw, hence an RFR.

The change made to the unshuffled patch is

-         String HTTPLOG = "sun.net.www.protocol.http.HttpURLConnection";
+         String HTTPLOG = "";


Bug: https://bugs.openjdk.java.net/browse/JDK-8183369
Webrev: https://cr.openjdk.java.net/~jdowland/webrevs/JDK-8183369/webrev.00/

Tested on Linux x86_64 with packet captures to verify what was going on
in addition to the logging output (which the test relies upon).

Thanks,
