> If a schema has an enum type with a default value, and the Builder API is
> used to automatically substitute the default value on build(), a
> ClassCastException is thrown. The reason is that the default value resolves
> to a GenericData.EnumSymbol. The specific builder then attempts to cast this
> value to the corresponding Java enum type, which fails. Here is an example
> stack trace:
> {noformat}
> org.apache.avro.AvroRuntimeException: java.lang.ClassCastException:
> org.apache.avro.generic.GenericData$EnumSymbol cannot be cast to
> org.apache.avro.ipc.specific.PrivacyType
> at org.apache.avro.ipc.specific.Person$Builder.build(Person.java:410)
> at
> org.apache.avro.specific.TestSpecificRecordBuilder.testSpecificBuilder(TestSpecificRecordBuilder.java:51)
> Caused by: java.lang.ClassCastException:
> org.apache.avro.generic.GenericData$EnumSymbol cannot be cast to
> org.apache.avro.ipc.specific.PrivacyType
> at org.apache.avro.ipc.specific.Person$Builder.build(Person.java:407)
