damccorm opened a new issue, #19702:
URL: https://github.com/apache/beam/issues/19702
RowCoder is currently public in sdk.coders, tempting people to use it
directly. But the Schemas API is written such that everyone should be using
SchemaCoder, and RowCoder should be an implementation detail.
Unfortunately this isn't a trivial change, I tried to do it and resolve the
few dependencies that cropped up, but running RowCoderTest yielded the
following error:
```

org.apache.beam.sdk.schemas.RowCoderGenerator$EncodeInstruction from class

java.lang.IllegalAccessError:
