[11u] RFR 8217094: HttpClient SSL race if a socket IOException is raised before ALPN is available

[Aleksey Shipilev]

Hi,

Please review the 11u backport.

Original bug:
  https://bugs.openjdk.java.net/browse/JDK-8217094

Original fix:
  http://hg.openjdk.java.net/jdk/jdk/rev/a47b8125b7cc

The patch applies cleanly, but the test cannot compile due to testlibrary changes.

11u webrev:
  http://cr.openjdk.java.net/~shade/8217094/webrev.11u.01/

It differs from the original version by this:
