Parametric inner classes have the same parametric tpye?

Question

The qestion I have is:
If you have a parametric inner class with the name of the type parameter the same as the one of the parametric "outer" class. Are they the same?
I think they should be, but I just made an obeservation that they probably aren't.
The follwing code does not compile
public class POC<E> {
    public Iterator<E> iterator() {
        return null;
    private class Magic<E> {
        private Iterator<E> iterator;
        public Magic() {
            Magic.this.iterator = POC.this.iterator();
}What actually bugs me, is the error I got:
incompatible types
found: java.uti.Iterator<E>
required: java.util.Iterator<E>
hu? To me this looks like a match.
I could get it to compile with an Instance of Iterator<E> passed to the constructor in stead of getting it by myself.
And I use 1.5rc

Probably because types E and T are not correlated:
public class POC<E> {
    public Iterator<E> iterator() {
        return null;
    private class Magic<T> {
        private Iterator<T> iterator;
        public Magic() {
            Magic.this.iterator = POC.this.iterator();
}The error message in this case is:
POC.java: : incompatible types
found   : java.util.Iterator<E>
required: java.util.Iterator<T>
            Magic.this.iterator = POC.this.iterator();I've succeded to compile the following two programs:
//1.
public class POC<E> {
    public Iterator<E> iterator() {
        return null;
    private class Magic<E> {
        private Iterator<E> iterator;
        public Magic() {
            POC<E>  p = new POC<E>();
            iterator = p.iterator();
// 2.
public class POC<E> {
    public static <E> Iterator<E> iterator() {
        return null;
    private static class Magic<E> {
        private Iterator<E> iterator;
        public Magic() {
            iterator = POC.iterator();
}Which one suits you best?
