Description

I had a quick look but didn't see this already raised. This program:

class ListWrapper {  
  @Delegate
  List myList
  
  @Delegate
  URL homepage
}

causes this error:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Code.groovy: -1: A transform used a generics containing ClassNode java.lang.Class <T extends java.lang.Object -> java.lang.Object> for the method public final java.lang.Object getContent([Ljava.lang.Class; param0) throws java.io.IOException { ... } directly. You are not suppposed to do this. Please create a new ClassNode refering 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.

The issue was related to a class node which didn't use generics but was an array type which component did use generics. Fixed on master and 1.8.x.
