OpenJDK11u: Backward incompatible behavior

Hi Alan,

It seems this issue could be related to jtreg test jdk/sun/security/ssl/SSLSocketImpl/
This test passed on JDK8 but fails on JDK11. The test was disabled by JDK-8196584 ( TLS 1.3 Implementation )
With patch provided this test works better but still fails. I’m trying to figure out if it is test or jdk issue.

> TLS 1.3 was a massive project. It went into jdk/jdk around June 2018. It's really important for changes like this to get as much testing, and interop testing, as possible. Several projects and individuals contributed by testing the EA builds and providing timing feedback and bug reports. We need more of this to be able to identify behavior changes like you reported because it's impossible for tests to catch everything.
