A bit late, but I'm finally checking out the latest version of xstream for
Applet compatibility. So far no luck. When I run the following code
inside of appletviewer it crashes on the "new XStream()" line. Code and
exception below. Am I doing something wrong or are there still issues that
need to be worked around? I'm using version 1.4.7 from Maven central
repository.
Thanks!

DomDriver(),new
ClassLoaderReference(r.getClass().getClassLoader()));
xstream.registerConverter(new
JavaBeanConverter(xstream.getMapper()));
return (T)xstream.fromXML(r);
}
