JDK11 Some core security tests fail on closed channel exception

With latest JDK11 (build 11-ea+25) the following tests fail due to closed channel exception:

• domain-management/src/test/java/org/jboss/as/domain/management/security/auditlog/AuditLogHandlerBootEnabledTestCase.java (resolved by JDK update)
• testsuite/domain/src/test/java/org/jboss/as/test/integration/domain/HTTPSManagementInterfaceTestCase.java
• testsuite/elytron/src/test/java/org/wildfly/test/integration/elytron/sasl/mgmt/KerberosNativeMgmtSaslTestCase.java
• testsuite/elytron/src/test/java/org/wildfly/test/integration/elytron/sasl/mgmt/ScramPlusMgmtSaslTestCase.java
• testsuite/manualmode/src/test/java/org/wildfly/core/test/standalone/mgmt/HTTPSManagementInterfaceTestCase.java

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

When these tests will start passing WFCORE 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-core/pull/3420
to fix known JDK11 issues.
