   Can't subclass ElementNode in applet

I've got an application which subclasses ElementNode with, for example, a
class com.artemisalliance.xml.ModelNode.  ModelNode implements some methods
which wrap various features of the Node interface.

This works fine when I have the com.sun.xml package exploded into my class
path for the IDE, but if I try to run it with the package in the jar,
either in the ide or in a browser, I get an IllegalAccessError:

java.lang.IllegalAccessError: try to access class
com/sun/xml/tree/ParentNode from class com/artemisalliance/xml/client/ModelNode

I've got three questions:

1) Why is ParentNode not a public class?

2) Why does the JVM throw this only when the package is jar'd?

3) Any ideas what I can do about this?  It would be very inconvenient not
to be able to subclass ElementNode.
