------------------------------------
Assignee: Eric Milles
> Script @groovy.transform.Field AST transformation generics handling with
> fully qualified types
> ----------------------------------------------------------------------------------------------
>
> Key: GROOVY-10516
> URL: https://issues.apache.org/jira/browse/GROOVY-10516
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.4.21, 2.5.15, 3.0.9
> Reporter: Frédéric Chuong
> Assignee: Eric Milles
> Priority: Minor
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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.
> @ line 1, column 1.

> {noformat}
> 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
