Bug fix [394]: When trying to access the optional Jython (or W3C DOM) classes has failed in DefaultObjectWrapper with an Error, rather than with an Exception, loading the DefaultObjectWrapper class itself has failed, instead of the Jython (or W3C DOM) support being disabled. From now in, it will survive any kind of Throwable there, and if the Throwable is not an ClassNotFoundException, it will also log the Throwable.
