Description

I am trying to write a hadoop example in Groovy and find groovy can not resolve type defined in super class written in Java:

Groovy version(qualified class name is required. Note: Reducer is written in Java)
https://github.com/danielsun1106/hadoop-wordcount/blob/master/src/main/groovy/me/sunlan/hadooplabs/wordcount/GroovyWordCount.groovy#L36

Java version(Only class name is enough)
https://github.com/danielsun1106/hadoop-wordcount/blob/master/src/main/java/me/sunlan/hadooplabs/wordcount/WordCount.java#L39

In the meanwhile, I find the issue does not exist if super class is written in Groovy too:

class Reducer {
    public abstract class Context {}
}

class Example extends Reducer {
    public void reduce(Context context) {}
}

new Example().reduce(null)
