Minor Description
Groovy 2.4.21 / 2.5.14 / 3.0.9
Script.groovy
@groovy.transform.Field java.util.List list
produces the following error:
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:
Script.groovy
@groovy.transform.Field List list
This also seems fine with Groovy 4.0.0
