Hi Richard,
I am under the impression that JDOM is again responsible for my problem.
The problem comes when calling
org.jdom.xpath.XPath.newInstance(XPath.java:134).
What do you think, should I just change my XML library and the drop this
JDOM that is making me crazy by not having a regular dependancies tree (that
causes BND to generate a stupid MANIFEST)?
Regards,
Renaud
