Hello, Jena developers!
I am trying to load the BTC-2009 dataset from SemSearch-2011 into tdb. (Jena 2.7.4) 

In chunk 13 there are some interesting quads:
http://www.swop-project.eu/swop-solutions/ontologies/wagemaker/lambda-mini_ligger.owl http://www.swop-project.eu/ontologies/wagemaker/lambda-mini_ligger.owl#minimaleBreedte http://www.swop-project.eu/ontologies/pmo/product.owl#defaultValue "190"^^http://www.w3.org/2001/XMLSchema#anySimpleType
http://www.swop-project.eu/swop-solutions/ontologies/wagemaker/lambda-mini_ligger.owl http://www.swop-project.eu/ontologies/wagemaker/lambda-mini_ligger.owl#diffWerkendeEffectieveBreedte http://www.swop-project.eu/ontologies/pmo/product.owl#defaultValue "10"^^http://www.w3.org/2001/XMLSchema#anySimpleType 

... etc.
They have xsd:anySimpleType.
riot --validate tells me that there are no errors, so this file can be loaded into tdb, right? 

But when I try to load it via tdbloader, I get the following:
http://www.swop-project.eu/swop-solutions/ontologies/wagemaker/lambda-mini_ligger.owl http://www.swop-project.eu/ontologies/wagemaker/lambda-mini_ligger.owl#diffWerkendeEffectieveBreedte http://www.swop-project.eu/ontologies/pmo/product.owl#defaultValue "10"^^http://www.w3.org/2001/XMLSchema#anySimpleType

I suppose that in method getFoundingType() there is no base type for xsd:anySimpleType, so we have null. 

/**
* Return the most specific type below xsd:anySimpleType that this type is derived from. 
     */
private XSTypeDefinition getFoundingType() {
        XSTypeDefinition founding = typeDeclaration;
        XSTypeDefinition parent = founding.getBaseType();
        while (parent.getBaseType() != null) {
            founding = parent;
            parent = founding.getBaseType();
        }
        return founding;

Is it a bug? I think jena should throw another exception.

Thanks.
Please, answer. Using xsd:anySimpleType is legal, riot --validate shows no ERROR strings. But tdbload crashes with NullPointerException. Is it Jena's problem or just invalid data? 

Thank you.
