[8u] RFR 8209333: Socket reset issue for TLS 1.3 socket close

[Alvarez, David]

Hi,

I would like a review for 8209333. This is one of the Socket related
patches that were applied to OpenJDK11 after the backport of TLS 1.3 to
OpenJDK8

BugId: https://bugs.openjdk.java.net/browse/JDK-8209333
Webrev: 
http://cr.openjdk.java.net/~alvdavi/webrevs/8209333/webrev.8u.jdk.00/

The only relevant differences are in SSLSocketImpl.java, as it
contained a java 9 try-with-resources block [1]. A
@SuppressWarnings("try") was needed.

All tests under sun/security/ssl pass after this change.

Thanks

David
