> While trying to upgrade our pipelines from Beam 2.11.0 to Beam 2.16.0 we found that our SpecificRecords used in PCollection were being decoded as GenericRecords.
> After some investigation we found the specific commit/issue that we think did brake it:
> [https://github.com/apache/beam/pull/8342/files]
> https://issues.apache.org/jira/browse/BEAM-7103
> After the mentioned change all AvroCoders are serialized as simple urn: "beam:coder:avro:v1" which means they are deserialized / rehydrated as AvroCoder<GenericRecord>.
