------------------------------
Summary: SpecificData.java has a bug creating a schema for a map
Key: AVRO-1148
URL: https://issues.apache.org/jira/browse/AVRO-1148
Project: Avro
Issue Type: Bug
Components: java
Affects Versions: 1.6.3
Environment: Mac
Reporter: Amine R.
in the SepcificData class, the protected Schema
createSchema(java.lang.reflect.Type type, Map<String,Schema> names) fails in
creating a schema for the Map type.
Looking at this excerpt,
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));
}
The type is a map, the key is a string. therefore instead of "if (!(type
instanceof Class" it should be "if (!(key instanceof Class".
