> abstract class A implements I {
> static void m(Number n) { print 'number' }
> }
> {code}
> {code:java}
> package p;
> public interface I {
> default void m(String s) { System.out.print("string"); }
> }
> {code}
> {code:groovy}
> @groovy.transform.CompileStatic
> class C extends p.A {
> void test() {
> m('') // error at run-time
> }
> }
> new C().test()
> {code}
> {code}
> org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast
> object 'class C' with class 'java.lang.Class' to class 'p.I'
