>                 URL: https://issues.apache.org/jira/browse/GROOVY-9606
>             Project: Groovy
>          Issue Type: Bug
>          Components: Stub generator / Joint compiler
>    Affects Versions: 2.5.6
>            Reporter: Keegan Witt
>            Assignee: Paul King
>            Priority: Major
>             Fix For: 4.0.0-alpha-1, 3.0.5, 2.5.13

> {code:groovy}
> trait SomeGroovyTrait<D> {
>     List<D> list(D arg) {
>         [arg]
>     }
> }
> class SomeGroovyClass implements SomeGroovyTrait<String> { }
> {code}
> Generates a stub like this
> {code:groovy}
> ...
> public class SomeGroovyClass implements SomeGroovyTrait<java.lang.String>, groovy.lang.GroovyObject {
>     ...
>     public  java.util.List<D> list(D arg) { return (java.util.List<D>)null;}    // <== D should be String
> }
> {code}
> Note that the return type and parameter types use {{D}} instead of type {{String}} and the generic reference isn't declared in the class either.
