[jdom-interest] Thread safe question: OK for simultaneous read-only access?

I'm writing something that generates interfaces for the public methods in jdom
classes, a default implementation (which implements the i/f and extends the
corresponding JDOM class), and optionally a SAXBuilder subclass to build using
the default implementations.
The problem is you get quite a large interface where many of the
implementations will be the same (helper methods eg getChildText) so I wonder
whether the i/f should contain only core methods and use helpers to do non
core things. This would mean I only have a subset of the documented API
available (but all of the functionality).
The application code will also contain more casting, eg:
IElement parent = (IElement) e.getParent();
Might it be easier to cheat and just make a customised org.jdom.Element which
implements IElement? This way I could use the org.jdom.output.* stuff too.
The reason I'm doing this is to use the JDOM API on things that aren't
subclasses of JDOM classes.

is that this kind of "wrappers" could be implemented very elegantly if JDOM
were designed in terms of interfaces + default implementation.
