Description
JDK-8161016 fixes the behavior of HttpURLConnection when using a  ProxySelector.  The fixed code does not use a direct connection, but moreover  it does not even retry to connect (before fixed, it does retry).  This behavior does not conform to HTTP (RFC 7230), which says idempotent methods retry to connect.

8u Review: https://mail.openjdk.java.net/pipermail/jdk8u-dev/2021-August/014153.html

Fix Request (8u) I'd like to backport this to 8u for parity with Oracle 8u311. It depends on JDK-8161016 first being backported. The patch applies cleanly after unshuffling, but the included test requires a change to the Logger that is configured, due to differences in logging behaviour before/after Jigsaw. RFR thread: https://mail.openjdk.java.net/pipermail/jdk8u-dev/2021-July/014116.html Thanks

Looks OK in the tests run barring timeout in JDK-8218466 (should be fixed in JDK-8236859)

Fix request (13u) I'd like to backport it to 13u as well. Patch applies cleanly (after JDK-8227539 which should be ported first).

Fix Request (11u) Backport to 11u requested because it is a part of 11.0.8-oracle. Patch does not apply cleanly to 11u because test depends on changes from JDK-8227539. Review thread: https://mail.openjdk.java.net/pipermail/jdk-updates-dev/2020-March/002894.html Test is included with the patch.

Fix Request (14u) As per RFC 7230 idempotent methods should do retry to connect .But HttpURLConnection connect() method is not having a retry with proxy if the connection fails on the first attempt.With the fix , connect() method will do retry with proxy.
