Description

After getting schema validation to work with aegis databinding, I noticed the ?wsdl is no longer working due to a NullPointerException. The relevant part of the stacktrace:

unwinding now: java.lang.NullPointerException
at org.apache.cxf.wstx_msv_validation.Stax2ValidationUtils.setupValidation(Stax2ValidationUtils.java:71) [cxf-wstx-msv-validation-2.4.1.jar:]

It seems that at AegisSchemaValidationInInterceptor:54 the result of message.getContent(XMLStreamReader.class) is null.

Obviously, a ?wsdl from a webbrowser is not a valid message, so a validation error could be expectable (a NPE isn't of course). I am wondering though if it is desirable, as it would leave ?wsdl broken.
