If you're only interested in an X's private data, you should
probably extract it explicitly and save it, rather than
trying to serialize the X object itself. The reason for
this is that some other class may need to save the state
of the entire X object, including any JTables it references.
(However, I was always under the impression that listeners
to Swing objects were NOT serialized by design; listeners
are transient. A JTable would be such a listener. I'm not
quite sure why this X object references a JTable
non-transiently.)
I could go into more detail about writing custom serialization
code, including externalization if it comes to that, but I'm
not even sure such things would be appropriate here.
