[jira] [Created] (GROOVY-10379) Error for super class and super interface methods of same name

Eric Milles created GROOVY-10379:
------------------------------------

             Summary: Error for super class and super interface methods of same name
                 Key: GROOVY-10379
                 URL: https://issues.apache.org/jira/browse/GROOVY-10379
             Project: Groovy
          Issue Type: Bug
            Reporter: Eric Milles


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'\r\n

	at org.codehaus.groovy.vmplugin.v8.IndyInterface.fromCache(IndyInterface.java:318)\r\n
	at Main.run(Main.groovy:7)\r\n
{code}
