             Summary: PutEmail Processor fails with Java 11
                 Key: NIFI-8281
                 URL: https://issues.apache.org/jira/browse/NIFI-8281
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 1.13.0
         Environment: Alpine base Docker Container based on 
`adoptopenjdk/openjdk11:alpine-jre`
            Reporter: Robin Lutz


I am sending a zip file as attachment via the PutEmail processor. When I 
upgraded to Java11, it stopped sending mails and also did not move them to the 
failure queue, but there is a exception/bulletin when it tries for the first 
time:

```2021-03-01 15:08:09,721 INFO [NiFi logging handler] org.apache.nifi.StdOut 
2021-03-01 15:08:09,719 WARN [Timer-Driven Process Thread-8] 
o.a.n.controller.tasks.ConnectableTask Administratively Yielding 
PutEmail[id=e8d3f418-8de4-358d-9ad3-e916e64eebe8] due to uncaught Exception: 
java.lang.NoClassDefFoundError: com/sun/activation/registries/LogSupport```

A similar error is reported here:
https://issues.apache.org/jira/browse/NIFI-6961

Replacing `javax.activation-api-1.2.0` by `javax.activation-1.2.0` also helps 
in this case.
