Java inner class creates weird schema

[tomdaffurn]

Using an inner class as data produces weird schema. The this$0 parent class reference confuses the schema extractor.

e.g.

public class ExampleModule {
    @Export
    @Verb
    public InnerClass TheVerb(InnerClass val) {
        return val;
    }

    public class InnerClass {
        private String field;
    }
}

Produces:

module example {
 export data ExampleModule {
 }

 export data InnerClass {
   field String
   this$0 example.ExampleModule
 }

 export verb TheVerb(example.InnerClass) example.InnerClass
}
