>             Project: Groovy
>          Issue Type: Bug
>          Components: Compiler
>    Affects Versions: 2.3.0
>            Reporter: Brongniart Jérôme
>            Priority: Major

> We are facing an issue when using the following groovy script is used as a ScriptBaseClass with version 2.3.0 or greater:
> {code:java}
> abstract class Templates extends Script {
>     def test() {
>         def a = [];
>         return a;
>     }
> }
> {code}
>  Error:
> {noformat}
> Script1.groovy: 1: A transform used a generics containing ClassNode Templates for the super class Script1 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.
> {noformat}
> The error happens when calling the following example (This example is working as expected when using Groovy 2.2.2):
> {code:java}
> import java.io.IOException;
> import org.codehaus.groovy.control.CompilationFailedException;
> import org.codehaus.groovy.control.CompilerConfiguration;
> import groovy.lang.GroovyShell;
> import groovy.lang.Script;
> public class GroovyTest {
> 	
> 	public static void main(String[] args) throws CompilationFailedException, IOException {
> 		CompilerConfiguration groovyCompilerConfiguration = new CompilerConfiguration();
> 		groovyCompilerConfiguration.setScriptBaseClass("Templates");
> 		groovyCompilerConfiguration.setDebug(true);
> 		groovyCompilerConfiguration.setVerbose(true);
> 		
> 		GroovyShell shell = new GroovyShell(groovyCompilerConfiguration);
> 		Script script = shell.parse("print \"test\"");
> 	}
> }
> {code}
> Is this an issue from Groovy or is this change expected?
> Thanks and regards
