That module defined on custom-handler looks wrong. I think it should likely beĀ org.apache.kafka.log4jappender.

Hi,

I'm following this guide to get logging sent to kafka: https://developer.jboss.org/wiki/SendingWildFlyLogsToKafka

This works on EAP 7.2.3.GA running on JDK 8, but fails to run on JDK 11:

```
15:54:28,819 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([
    ("subsystem" => "logging"),
    ("custom-handler" => "kafka")
]): java.lang.IllegalArgumentException: Failed to load module "org.apache.log4j" for pojo "kafka"
...
```
Do you think this is related to the new module system in JDK 11 and I need to add some extra JVM flags to get it to work?
Thank you for your help!

Sincerely,
Dustin
