[volker dot berlin at goebel-clan dot de]

The follow lines produce the follow NPE with classpath. The same code work with
Sun Java VM. Off course this is not a real code but it show the problem very
simple with extended classes. The exception occur in the constructor and I have
no chance to init my class.

=================== 
JComboBox box = new JComboBox(){
    public ComboBoxEditor getEditor(){
        return null;
    }
};

====================
Exception in thread "main" java.lang.NullPointerException
