["Paul King (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-6653?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17368595#comment-17368595 ] 

Paul King commented on GROOVY-6653:
-----------------------------------

A workaround is to add {{@CompileStatic}} to {{D#getText}} in cases where no dynamic behavior is needed.

> You can get StackOverflowError when running following code:
> {code:title=A.java}
> package test.java;
> public abstract class A<T> {
>     protected String getText(T arg){
>         return "Class A.";
>     }
> }
> {code}
> {code:title=C.java}
> package test.java;
> public class C extends A<String> {
>     @Override
>     protected String getText(String arg){
>         return super.getText(arg) + "Class C. ";
>     }
> }
> {code}
> {code:title=D.groovy}
> package test.java
> class D extends C {
>     @Override
>     protected String getText(String arg) {
>         return super.getText(arg) + 'Class D.';
>     }
>     public static void main(String[] args) {
>         D d = new D();
>         String res = d.getText(null);
>         println(res);
>     }
> }
> {code}
> This bug occurs when class A is generic and method has parameterized argument.
> {code:title=Output}
