NoClassDefFoundError after updating to latest Java on OS X

Hi all,

I'm running into a problem after updating to the latest Java version  
on OS X. It doesn't affect most Pivot development, but it does break  
the JFreeChart-based charting provider. I get this exception at  
application startup:

Exception in thread "main" java.lang.NoClassDefFoundError: apple/laf/ 
CoreUIControl

This class appears to be missing in the latest update. A simple test  
case will reproduce it:

import javax.swing.JButton;

public class CoreUIControl {
     public static void main(String[] args) {
         new JButton();
     }
}

I also can no longer edit the properties for JVM 1.6.0 in the  
"Installed JREs" preferences in Eclipse.

I'm planning to file a bug to Apple - is anyone else seeing this  
problem?

FYI, I found a workaround to the Eclipse problem - just wanted to pass it along in case anyone else runs into this:

- Create a new 1.6.0 JVM in Eclipse (I called it "1.6.0x")
- Delete the old 1.6.0 JVM
- Re-create the 1.6.0 JVM as a copy of 1.6.0x
- Delete the 1.6.0x JVM

FYI, this only appears to affect execution in Eclipse. Running the  
sample from the command line works OK.
