The spec http://avro.apache.org/docs/1.5.3/spec.html#Names
states that names must:

          
* start with [A-Za-z_]
          
* subsequently contain only [A-Za-z0-9_]
	

Unfortunately, Java inner classes contain $.

Sometimes, avro uses $ internally to disambiguate names, since if it
creates a field or method with '$' in it that can't conflict with a user
created one.  

Can you open a JIRA to discuss this limitation further?

Thanks!
