Re: [xml-dev] contradictory loader ordering in 3.5

Hello Rich,

while trying to interpret the exception message I see
following edge description:

com.nuance.tools.voicexml.VoiceXMLDataLoader@1d29a78=[com.nuance.tools.voicexml.VoiceXMLDataLoader@1d29a78]

It's clean cycle. How does it get into play? Is it generated by
loaders system? Do you have all manifest without the dependency?

   Cc.

PS: You can also hack Utilities.topologicalSort() to ignore
such "identity edges".
