Midlet Development: class file for java.lang.NoClassDefFoundError not found

I have been experimenting a little with writing a mobile application in Java. Most of the basics seem fairly easy, given my background in VB.Net and C#. Other things, however, are baffling, or just plain frustrating.

The version of Java I am using doesn’t support emumerated types, so I am using a nice little class I found on the web to emulate them. In my code there is a class like this:

class GxHorizontalAlignment extends UtilEnum {

private GxHorizontalAlignment(String name) {super( name, GxHorizontalAlignment.class );
}

public static GxHorizontalAlignment Left = new GxHorizontalAlignment("Left");
public static GxHorizontalAlignment Center = new GxHorizontalAlignment("Center");
public static GxHorizontalAlignment Right = new GxHorizontalAlignment("Right");

}

I have been battling for a few days with an error in an error in”GxHorizontalAlignment.class” which reads:

class file for java.lang.NoClassDefFoundError not found
super( name, GxHorizontalAlignment.class );
^1 error

Switching from CLDC-1.0 to CLDC-1.1 makes the error go away.

SDN Bug ID 4313429 seems to explain things somewhat. However, without a proper work-around I will either be forced to target only CLDC 1.1 devices, or abandon this method of simulating enums.
