JConfigurationFactory gives the following error message when parsing the attached configuration file:

invalid XML configuration: XML protocol stack configuration does not start with a '<config>' element; maybe the XML configuration needs to be converted to the new format ?
use 'java org.jgroups.conf.XmlConfigurator <old XML file> -new_format' to do so

The attached file does indeed start with a 'config' element. Looking at the code, JConfigurationFactory is actually looking for a 'protocol_stacks' root element.

the error message in JConfigurationFactory should be fixed.

Furthermore, the -new_format argument doesn't appear to be accepted by XmlConfigurator. XmlConfigurator also seems to like the XML file if it starts with <config>. So which is the right format? All of the examples provided with the distribution start with <config>.
