> The situation are similar as awt module. Many persistence delegates are not properly implemented for swing package.The following test case will reveal this.
> public void test_writeObject_javax_swing_Box() {
>         ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
>         XMLEncoder encoder = new XMLEncoder(new BufferedOutputStream(byteArrayOutputStream));
>         Box box = new Box(1);
>         box.setAlignmentX(12.21f);
>         encoder.writeObject(box);
>         encoder.close();
>         DataInputStream stream = new DataInputStream(new ByteArrayInputStream(byteArrayOutputStream.toByteArray()));
>         XMLDecoder decoder = new XMLDecoder(stream);
>         Box aBox = (Box) decoder.readObject();
>         assertEquals(box.getAlignmentX(), aBox.getAlignmentX());
>     }
> This test case passes on RI, but will throw NullPointerException on harmony.
> The swing classes need special treatment are:
> Box,
> JFrame,
> JTabbedPane,
> DefaultComboBoxModel,
> ToolTipManager
