> Follow up to GROOVY-9737.  Another variation of static and non-static (interface default in this case) methods of the same name.  Consider the following:
> {code:groovy}
> package p
> 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'
> 	at org.codehaus.groovy.runtime.typehandling.DefaultTypeTransformation.continueCastOnSAM(DefaultTypeTransformation.java:420)
> 	at org.codehaus.groovy.runtime.typehandling.DefaultTypeTransformation.continueCastOnNumber(DefaultTypeTransformation.java:331)
> 	at org.codehaus.groovy.runtime.typehandling.DefaultTypeTransformation.castToType(DefaultTypeTransformation.java:251)
> 	at org.codehaus.groovy.vmplugin.v8.IndyInterface.fromCache(IndyInterface.java:318)
> 	at C.test(Main.groovy:4)
> 	at org.codehaus.groovy.vmplugin.v8.IndyInterface.fromCache(IndyInterface.java:318)
> 	at Main.run(Main.groovy:7)
> {code}
