Description

Hi Everyone

I'm using Groovy 1.8.2, and there's a variant of http://jira.codehaus.org/browse/GROOVY-4884. This code fails for me:

import org.junit.Test;

public class BreakingExample_NoMetaclassOverride {
   @Test
   void testNotOverriden() {
      def list = []
      ClassUnderTest cut = new ClassUnderTest()
      cut.metaClass.getRemoteObject = { ->
         return [method: {obj -> 
            list << obj
         }] as RemoteObject
      }
      
      String val = "Value" 
      cut.someMethod(val)
      assert list == [val]
   }
}

public class ClassUnderTest extends RemoteObject {
   public def someMethod(String someValue) {
      RemoteObject object = getRemoteObject()
      object.method(someValue)
   }
   protected RemoteObject getRemoteObject() {
      return new RemoteObject()
   }
}

public class RemoteObject {
   public void method(obj) { /* Something */ }
}

The only difference between this and #4884 is the "extends RemoteObject" added to ClassUnderTest. With it in, the test fails. Remove it, the test passes.

Please let me know if you need any more info!

Thanks
