> "My class is declared as follows:
> @DefaultCoder(SerializableCoder.class) public class Data<DataT extends 
> BaseData> implements Serializable {
> and it fails like this:
> Caused by: org.apache.beam.sdk.coders.CannotProvideCoderException: Cannot 
> provide coder based on value with class my.project.Data: No CoderFactory has 
> been registered for the class."
> It seems like this should work, though Create's value-based coder inference 
> has more limitations and safety issues than usual coder inference. To 
> investigate.
