Use JComboBox as it's own ActionListener leads to unexpected behaviour

FULL PRODUCT VERSION :
1.7.0_06

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows 6.1.7601

A DESCRIPTION OF THE PROBLEM :
If you use a JComboBox as it's own ActionListener you will get unexpected behaviour:

The entries become (visually) unselectable.

This problem encounters especially when inheriting a class from JComboBox that implements an ActionListener

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. create a (not-empty) JComboBox
2. use it as it's own ActionListener
3. add it to a Window/Dialog/Frame/Panel and run it
4. select an entry, different from the first one

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
An entry should get selected
ACTUAL -
No entry is selected

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
public static void main(String[] args) {

JDialog dialog = new JDialog();

String[] entries = { " Cats " , " Porn " , " Lazors " , " Memes " };

// here starts the relevant part
JComboBox<String> myComboBox = new JComboBox<String>(entries);
myComboBox.addActionListener(myComboBox);
// here ends the relevant part

dialog.add(myComboBox);
dialog.pack();
dialog.setVisible(true);

}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
If you need to inherit a class from JComboBox and you want to have it's own Listener, don't use ActionListener, use ItemListener instead.
