Description

Copied from the mailing list report:

I think the method AvroUtils.toBeamSchema has a not expected side effect.
I found out that, if you invoke it and then you run a pipeline of GenericRecords containing a timestamp (l tried with logical-type timestamp-millis), Beam converts such timestamp from long to org.joda.time.DateTime. Even if you don't apply any transformation to the pipeline.
Do you think it's a bug?
