Notepad save problem (Build 7)

I am using the Notepad demo on the ignoramus site.
Enable the console in javaws.
When you click save, after granting the permission, then click cancel in the
File save window, you will see the following exceptions:

TH: java.lang.reflect.InvocationTargetException
java.lang.reflect.InvocationTargetException: java.lang.ClassCastException: java.lang.Boolean
