> protocol MyService {
> record Bar {
> int count;
> string message;
> }
> map<Bar> getBars();
> }
> {code}
> generates run-time errors because of this code in SpecificData.java

> } else if (Map.class.isAssignableFrom(raw)) { // map
> java.lang.reflect.Type key = params[0];
> java.lang.reflect.Type value = params[1];
> if (!(type instanceof Class
> && CharSequence.class.isAssignableFrom((Class)type)))
> throw new AvroTypeException("Map key class not CharSequence: "+key);
> return Schema.createMap(createSchema(value, names));
