Hi Joe,

Judging from the source in the newly published jdk6 bundle (b05-12_feb_2008), it appears the fix for this bug is included:

file: java/util/prefs/XmlSupport

    /**
     * Write XML document to the specified output stream.
     */
    private static final void writeDoc(Document doc, OutputStream out)
        throws IOException
    {
        try {
            TransformerFactory tf = TransformerFactory.newInstance();
            try {
                tf.setAttribute("indent-number", new Integer(2));
            } catch (IllegalArgumentException iae) {
                //Ignore the IAE. Should not fail the writeout even the
                //transformer provider does not support "indent-number".
            }
...

Cool. Now how do I figure out when/if this code will make it into a release of jdk/jre 1.6? Dare I infer the "b05" might translate to jdk6 update 5?

Thanks,
Dan
