----------------------------------

             Summary: Certificate compatibility broken for JDK8 build running on JRE11
                 Key: NIFI-6561
                 URL: https://issues.apache.org/jira/browse/NIFI-6561
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Security
    Affects Versions: 1.10.0
            Reporter: Nathan Gough


When testing Java 11 build compatibility, I found an issue with TLS certificates when using
a remote process group looped back to an input port on the same cluster. The same certificates
were used for JDK8/JRE8, JDK8/JRE11, JDK11/JRE11 ie. they contained relevant SAN entries in
each case.

*Building on JDK 1.8.0_172 and run on JRE11.0.5+10 caused exceptions when attempting to send
to local input port with RPG*:
