Re: jdom2 runtime

OK, I believe the issue is an incompatible issue with crimson. I believe 
you have xrimson earlier in the classpath than xerces, as a result the 
JAXP process is choosing the crimson parser instead of xerces.

You should be able to check this by adding "-Djaxp.debug=1" to your jvm 
arguments.

Crimson is *really* old... the most recent release was in 2001.... and 
it is discontinued. Though I am surprised it even has any JAXP 
vestiges... though, checking it's documentation, it *does* support JAXP 
1.1, thus, I imagine what is happening in your case is that you have 
Crimson earlier in the classpath than xerces. As a result, the JAP API 
is finding the crimson parser ahead of the Xerces.

I recommend dropping the crimson jar from your classpath. There is 
nothing you should be needing Crimson for (and if you have 
third-party-dependencies requiring crimson then there's problems).

Alternatively, put the xerces jar at the top of the classpath.

With the fix for issue #89 (not available yet) you can specify the 
xerces JAXP factory explicitly....

For the record, the 'simple' circumstance is for there to be just one 
XML parser in your classpath... not two.

I recommend using the xerces.jar and matching xmlapis.jar only

For what it's worth, the other jars Xalan, saxon, etc, are not actual 
parsers, but rather additional XML functionality.
