-----------------------------
Summary: Java: ReflectData incorrectly handles hidden fields
Key: AVRO-2808
URL: https://issues.apache.org/jira/browse/AVRO-2808
Project: Apache Avro
Issue Type: Bug
Components: java
Reporter: Andy Le
Hi guys,
I've got the following test:
{code:java}
public ReflectTest{
public class Definition {
public Map<String, Type> tokens;
}
public enum Type {
A,
B,
C
}
@Test
public void testAvro2805() {
Schema schema = ReflectData.get().getSchema(Definition.class);
final String schemaString = schema.toString(true);
System.out.println(schemaString);
}
}
{code}
When I ran the test, an exception is raised:
{noformat}
org.apache.avro.SchemaParseException: Illegal character in: this$0

>From the log, you may see that: we should not handle Java hidden field
>`this$0` which is used to hold reference to outer class instances.
