archetype create swallows exception information

The DefaultPomManager.java contains:

catch ( JDOMException exc )

all exc info is lost. My particular problem was that the archetype pom contained:

#set( $symbol_dollar = '$' )
#set( $symbol_lt = '<' )
#set( $symbol_gt = '>' )

<?xml version="1.0" encoding="UTF-8"?>

and the space before the xml declaration was throwing the previous exception.

I attach a very simple patch to make it easier to track these errors. It was generated with svn diff > jdom-error-message.txt against maven-archetype-2.0-alpha-4.
