> I want to use Avro from Scala, i.e. generate case classes from an Avro schema. So far
this is working fine except for one thing - fields in Scala classes are always private. This
doesn't work with Avro SpecificRecords (at least when inferring the schema from the class)
and results in the following exception:
> org.apache.avro.AvroRuntimeException: java.lang.IllegalAccessException: Class org.apache.avro.specific.SpecificData
can not access a member of class <my.Class> with modifiers "private"
> The exception is thrown from the following line in org.apache.avro.specific.SpecificData:
> schema = (Schema)(c.getDeclaredField("SCHEMA$").get(null));
> My suggestion would be to additionally check for a method called `getSchema` and read
the schema from that method.
