So, I've updated the PR. Sorry for force-pushing, hope you didn't review the 
code in detail yet.

The new version updates module-info as requested. I also enhanced the test 
`LdapSSLHandshakeFailureTest.java` and added variants that exercise a Socket 
Factory which does not support unconnected sockets. Two of the test variants 
would fail with the current JDK.
