Is there a known SSL issue in JDK11? Could somebody from our security team investigate this issue?

When these tests will start passing WF test suite will be passing 100% of tests on JDK11.

Potential investigator from our security team may want to include this PR:
https://github.com/wildfly/wildfly/pull/11499
to fix known JDK11 issues.
