Description

I'm trying to use XMLPropertyListConfiguration to load a property-list from a byte array. My code looks like:

XMLPropertyListConfiguration plist = new XMLPropertyListConfiguration();
// plist.setRootNode(new PListNode()); // HACK to work around internal cast exception
plist.load(new ByteArrayInputStream(bytes));

This causes a ConfigurationException caused by a class exception (reproduced below). The exception can be avoided by uncommenting the second line.
