[8u] RFR 8228757: Fail fast if the handshake type is unknown

[Martin Balao]

Hi,

I'd like to request a review for the 8u backport of JDK-8228757 [1].

Webrev.00:

 *
http://cr.openjdk.java.net/~mbalao/webrevs/8228757/8228757.webrev.jdk8u.jdk.00/

Changes from 11u:

 * Changes in the 'DTLSInputRecord.java' file do not apply to 8u because
there is no DTLS support in 8u. See JDK-8245469 [2].

 * In 'SSLEngineInputRecord.java' file, the copyright end date in 8u is
greater than in the patch because 8u has JDK-8245417 [3]. So the
copyright end date change does not apply.

No regressions found in jdk/sun/security/ssl tests category.

Thanks,
Martin.-
