Erro do compilador ou eclipse?

package br;

public class A {
	protected static void clean(Container container) {
		Component comps[] = container.getComponents();
		for (Component comp : comps) {
			System.out.println(comp.getClass().getCanonicalName());
			if (comp instanceof JRootPane || comp instanceof JPanel
					|| comp instanceof JLayeredPane)
				clean((Container) comp);
			if (comp instanceof JTextField)
				((JTextField) comp).setText("");
		}
	}
}

package br;

import static br.A.clean;

import javax.swing.JInternalFrame;

public abstract class B extends JInternalFrame {
	public void clean() {
	   clean(this);
	}
}

The method clean() in the type B is not applicable for the arguments (B)

clean(this);

A.clean(this);
