Description

When within SwingBuilder.edt, the instantiation of anonymous inner classes to appears to be broken.

Example code:

import groovy.swing.SwingBuilder
import javax.swing.SwingWorker;
import javax.swing.JFrame
import java.awt.BorderLayout

class TestEDT {
    public static void main( String[] args )
    {
        def myLabel
        def swing = new SwingBuilder()
        swing.edt {
            frame(pack:true, show:true, defaultCloseOperation:JFrame.EXIT_ON_CLOSE){
                borderLayout()
                myLabel = label("Hello", constraints:BorderLayout.CENTER)
            }

            def sw = new SwingWorker() {
                protected Object doInBackground() throws Exception
                {
                    return 10
                }
                protected void done()
                {
                    myLabel.text = get()
                }
            }.execute();
        }
    }
}

This throws:
