Paul King updated GROOVY-6653:
------------------------------
    Description: 
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}
Exception in thread "main" java.lang.StackOverflowError

This bug looks similar to GROOVY-5385
