Handle UnsupportedOperationException when creating XSDVALIDATING.

[stefanbirkner]

The SAXParserFactory throws an UnsupportedOperationException when setSchema
is called. Therefore every factory throws this exception unless it overrides
setSchema. A popular example is Apache Xerces SAXParserFactoryImpl before
version 2.7.0.

Makes sense. Can you comment on the rest of the functionality with 'old' xerces versions...? Is everything else working out OK?

Just looking at the code, I think it would be useful to 'preserve' the actual exception, so that the original exception can be identified. I am going to tweak that area of code a little.

Crap, put the wrong issue number on that commit.

Hi Stefan.
Normally I would build a 'hotfix' package including this fix, and then post it to the jdom downloads page. In this case through, I have a bunch of un-committed dev code in my environment, and I would rather wait a bit. On the other hand, if you would find a quasi-official jdom-2.x-issues93through95.zip useful then I can arrange it. I will assume not unless you tell me otherwise.

I don't need a hotfix package very soon. I'm using another SAXParserFactory in the meantime: http://coderwall.com/p/kqsrrw
