> Currently SchemaBuilder is strict when checking that certain fields have not
> been set yet (e.g. version, name, doc). It just checks that the field is
> null. This is intended to protect the user from buggy code that overwrites a
> field with different values, but it's a bit too strict currently. In generic
> code for converting schemas (e.g. Converters) you will sometimes initialize a
> builder with these values (e.g. because you get a SchemaBuilder for a logical
> type, which sets name & version), but then have generic code for setting name
> & version from the source schema.
> We saw this bug in practice with Confluent's AvroConverter, so it's likely it
> could trip up others as well. You can work around the issue, but it would be
> nice if exceptions were only thrown if you try to overwrite an existing value
> with a different value.
