> h1. Reproduction
> The compiler should not pass the given code and should give a "name clash" on
> method "func" in class "A"
> {code:groovy}
> public interface I<T> {
> public abstract void func(I<Object> arg1);
> }
> public abstract class A extends Object implements I<Object> {
> public final void func(I<String> arg1) {
> }
> } {code}
> h1. Expect output
> If class A is a Java class, you can see the error that should be reported by
> groovyc in javac output.
> {code:java}
> A.java:2: error: name clash: func(I<String>) in A and func(I<Object>) in I
> have the same erasure, yet neither overrides the other
> public final void func(I<String> arg1) {
> ^
> 1 error {code}
