[jdom-interest] Possible BUG in XercesErrHandler class

[Govy Munamala]

Thanks for the quick update. However, the SAXBuilder uses  
org.jdom.input.SAXHandler which has the same behaviour. The exceptions are 
being rethrown in both error & Warning methods. Do you think these methods 
could be changed to no op?

Thanks
Govy
