@dossett yes I have been able to reproduce the error, and it appears to
somehow be related to this pull request.
```
mvn clean install -DskipTests
cd examples/strom-starter
mvn clean test
```
The above works on master but fails 100% of the time with this pull
request. I see some ClassDef like issues so my guess is that the dependencies
are somehow messed up, probably with log4j.

> It receives Avro GenericRecord objects, which leads to serialization errors
> in a multi-worker topology. Specifically, GenericData.Record will throw a
> serialization error.
> A serializer for this class should be added and registered.
