XMLEncoder runtime problem

I'm trying to use XMLEncode for the first time.

I have a simple class TextPanel which extends JTextPane. It overrides the paint() method and adds a setRotation() and getRotation() method. The few member variables all have get/set methods.

When I apply encoder.writeObject() to an instance of TextPanel I get this message:

java.lang.IllegalAccessException: Class sun.reflect.misc.Trampoline

can not access a member ofclass TextPanel with modifiers""

Continuing ...

java.lang.Exception: XMLEncoder: discarding statement XMLEncoder.writeObject(TextPanel);

Continuing ...

Can anyone give me any clues regarding what this message means? It seems to be telling me I don't have the necessary get/set methods, but I do.

Thanks for any help.
