[jira] [Commented] (GROOVY-9170) The method clone should be public as it implements the corresponding method from interface java.lang.Object

Eric Milles commented on GROOVY-9170:
-------------------------------------

This error comes from {{Verifier.addCovariantMethods}}.  Default dynamic, {{@CompileStatic}} and {{@TypeChecked}} all produce the same error.

>                 URL: https://issues.apache.org/jira/browse/GROOVY-9170
>             Project: Groovy
>          Issue Type: Bug
>          Components: Compiler
>    Affects Versions: 2.5.7
>            Reporter: Mauro Molinari
>            Priority: Major
>
> I have a class like the following:
> {code:groovy}
> @CompileStatic
> class MyClass implements Serializable, Cloneable {
>   @Override
>   protected Object clone() {
>     super.clone()
>   }
> }
> {code}
> When trying to compile this class I get the following error from the Groovy compiler: {{The method clone should be public as it implements the corresponding method from interface java.lang.Object}}.
> Apart from the fact that {{java.lang.Object}} is not an interface ;-) it doesn't make sense. {{java.lang.Object.clone()}} is {{protected}} so why can't I override it and keep it {{protected}}?
