Marat Kamalov reopened GROOVY-10995:
------------------------------------
> Classes are compiled in Groovy 3 and Java but fails in Groovy 4
> ---------------------------------------------------------------
>
> Key: GROOVY-10995
> URL: https://issues.apache.org/jira/browse/GROOVY-10995
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 4.0.10
> Reporter: Marat Kamalov
> Priority: Major
>
> We use Groovy 3. And I tried to migrate the existing application to use
> Groovy 4.
> I have a compilation issue in the code and the same behavior in IntelliJ
> IDEA, because it uses Groovy 4 syntax by default.
> What I have:
> {code:java}
> // A simple interface with generic parameter
> // This is Java class compiled by Java
> interface MyInterface<T> {
> } {code}
> {code:java}
> // A simple annotation that expects an MyInterface implemenations
> // This is Java class compiled by Java
> @Retention(RetentionPolicy.RUNTIME)
> @Target(ElementType.METHOD)
> @interface MyAnnotation {
> Class<? extends MyInterface<?>> value()
> } {code}
> {code:java}
> //A class that implements MyInterface and ignores type raw type using warnings
> //This is Groovy class located at the same package with the next code
> public class MyClass implements MyInterface {
> }
> {code}
> {code:java}
> // A method that uses MyAnnotation with MyClass parameter
> //This is Groovy code that fails and located at the same package with MyClass
> @MyAnnotation(value = com.example.MyClass)
> static void main(String[] args) {
> }{code}
> This code compiles in Groovy 3 and compiles in Java but fails to compile in
> Groovy 4.0.10
> The code starts to compile in Groovy 4 If I change MyClass implementation to:
> {code:java}
> public class MyClass implements MyInterface<Object> {
> } {code}
> I think it is a bug, please, validate and fix it.
