But wait, there's more:

Here's the code in question:
 XMLInputFactory factory;

        try {
            // Woodstox is the only supported and tested StAX implementation
            WstxInputFactory wstxFactory = (WstxInputFactory)
ClassLoaderUtil.loadClass(
                    "com.ctc.wstx.stax.WstxInputFactory").newInstance();
            wstxFactory.configureForSpeed();

            factory = wstxFactory;
        } catch (Exception e) {
            // other StAX implementations may work, too
            factory = XMLInputFactory.newInstance();

            try {
                // for the SJSXP parser
                factory.setProperty("reuse-instance", Boolean.FALSE);
            } catch (IllegalArgumentException ex) {
                // ignore
            }

            LOG.warn("Unsupported StAX parser: " +
factory.getClass().getName() + " (Exception: " + e.toString() + ")",
                    e);
        }

The exception occurs in the try block and then we proceed into the catch
block, where factory = XMLInputFactory.newInstance() kicks in and works!

Guess what StAX parser it loads?  Yep: com.ctc.wstx.stax.WstxInputFactory.
Go figure.  And everything works fine after that.
