Description

I'm integrating "Xerces-J 2.11.0-xml-schema-1.1-beta" in Oxygen XML Editor.

After the integration one of our automated tests caught this NPE:

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

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

Basically the XMLSchemaValidator has some code like:
-----------------------
if (attDV.getVariety() == XSSimpleTypeDefinition.VARIETY_UNION) {
if (XSTypeHelper.isAtomicValueValidForAnUnion(attDV.getMemberTypes(),
null,
defaultValue))

{ fisAtomicValueValid = false; }

}
-------------------------

which sends a "null" value to the content parameter of "isAtomicValueValidForAnUnion" which later generates the NPE.

I will attach a WSDL file (the problem seems to happen when validating any WSDL file) and the "wsdl11soap11.xsd" schema.
