You might try something like this:

    textPane.getDocument().addDocumentListener( new DocumentListener() {
        void changedUpdate( DocumentEvent event ) {}
        void removeUpdate( DocumentEvent event ) {}
        void insertUpdate( DocumentEvent event ) {
            Document doc = event.getDocument();
            int len = doc.getLength();
            if ( len > 200 ) {
                try {
                    doc.remove( 200, len - 200 );
                } catch ( BadLocationException ex ) {
                    //  Not likely to happen.
                }
            }
        }
    } );

Note:  I have not tried to compile or run this, so it could have an 
error.  Debugging is left as an exercise for the programmer.
