A DESCRIPTION OF THE PROBLEM :
Compiling the attached source emits the following error message:

21: incompatible types
found : java.util.Iterator<R>
required: java.util.Iterator<R>

I cannot see what might be wrong with the source, but in any case the error message is not helpful.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
compile the sample source

1 error


REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import java.util.Iterator;

class MyIterator<R> implements Iterator<R> {
  public void remove() {
  }

  public R next() {

  public boolean hasNext() {
    return false;
  }
}

class MyClass<R> {
  final Iterator<R> iterator = new MyIterator<R>();

  class IterableImpl<R> implements Iterable<R> {
    public Iterator<R> iterator() {
      return iterator;
    }
