Consider the following Java class:

package test9;
public class Outer {
  public static enum MyEnum {
	  A, B;
  }
}

And the following Groovy class:

package test9
import test9.Outer.MyEnum
class GroovyClass {
	void doSomething() {
		MyEnum myEnum = MyEnum.A
	}
}

Now refactor Outer class and rename it to Outer2.
The following line in GroovyClass is not updated:
import test9.Outer.MyEnum
