-------------------------------------------------------------

The same {{Configuration}} instance can now be used to create several validator factories. In case any XML mapping streams are passed to the configuration, they are re-read whenever {{buildValidatorFactory()}} is invoked. In order to do so, the mapping streams are wrapped into {{BufferedInputStream}} s in case the original streams don't support the mark/reset contract.

> Currently invoking {{buildValidatorFactory}} several times on one {{Configuration}} instance results in an NPE. While the spec currently doesn't clearly say whether invoking {{buildValidatorFactory}} more than once is legal or not, I personally think we should support that use case.
