[11u] RFR: 7146776: deadlock between URLStreamHandler.getHostAddress and file.Handler.openconnection

[Doerr, Martin]

Hi,

JDK-7146776 is backported to 11.0.11-oracle. I'd like to backport it for parity.
Change doesn't apply cleanly because of Copyright year changes and a minor difference in a hunk which gets removed by this change:
11u Code contains host.equals(""), patch wants to remove host.isEmpty() from URLStreamHandler.java.

Bug:
https://bugs.openjdk.java.net/browse/JDK-7146776

Original change:
https://git.openjdk.java.net/jdk/commit/db9c114d

11u backport:

Please review.

Best regards,
Martin
