[jdom-interest] malformed URL exception exception in saxbuilder.build due to unreachable URL

[cliff palmer]

Rolf, that sounds like a great idea.
Another validation process that would help when doing XML exploration
(i.e you don't know what is in the data and are trying to find out)
would be to throw an exception of the string is null and not use the
"null pointer" exception.
Thanks again for your help.
Cliff
