>             Project: Groovy
>          Issue Type: Bug
>    Affects Versions: 2.4.21, 2.5.15, 3.0.9
>            Reporter: Frédéric Chuong
>            Priority: Minor
>
> Groovy 2.4.21 / 2.5.14 / 3.0.9
> {code:groovy|title=Script.groovy|borderColor=red}
> @groovy.transform.Field
> java.util.List list
> {code}
> produces the following error:
> {noformat}
> startup failed:
> xxx\Script.groovy: 1: A transform used a generics containing ClassNode java.util.List <E extends java.lang.Object> for the field list directly. You are not supposed to do this. Please create a new ClassNode referring to the old ClassNode and use the new ClassNode instead of the old one. Otherwise the compiler will create wrong descriptors and a potential NullPointerException in TypeResolver in the OpenJDK. If this is not your own doing, please report this bug to the writer of the transform.

> This does not happen when the code relies on implicit imports:
> {code:groovy|title=Script.groovy|borderColor=green}
> @groovy.transform.Field
> List list
> {code}
> This also seems fine with Groovy 4.0.0
