StaxSource is not supported for validation, VDB deployment fails

"apache.xerces" is used by default in the AS7 as the chosen jaxp library, and it does not support StaxSource as the Validator input. Consider using some other type of source like StreamSource.

Caused by: java.lang.IllegalArgumentException: Source parameter of type 'javax.xml.transform.stax.StAXSource' is not accepted by this validator.
