Impossibile trovare il simbolo (classe dentro lo stesso package)

[Kurapika]

Ciao a tutti,
ho un piccolo quesito da proporre

package customized;

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;

public class JComponentManager extends MouseAdapter
{
...
}

e la classe successiva usa la precedente

package customized;

public class CJRootPane extends javax.swing.JRootPane
{
  JComponentManager c = new JComponentManager(this);
  
  public CJRootPane(){}
}

la prima compila e tutto ok; la seconda nn va e mi dice:

CJRootPane.java:12: cannot find symbol
symbol : class JComponentManager
location: class customized.CJRootPane
JComponentManager c = new JComponentManager(this);
^
CJRootPane.java:12: cannot find symbol
symbol : class JComponentManager
location: class customized.CJRootPane
JComponentManager c = new JComponentManager(this);
^
2 errors



perché?
