> If you define a trait with generic type T and have a static method that return that type, compilation will fail with the following message:
> {code:java}
> Error:(5, 5) Groovyc: unable to resolve class T{code}
> Simple code for reproducing this bug:
> {code:java}
> trait MyTrait<T extends List> {
>     static T myMethod() {
>         return [1, 2, 3]
>     }
> }{code}
>  Groovy 2.4.x does not have this issue, from my testing this only happen in 2.5.x
