        Description

        XJC generates incorrectly annotation @XmlSchemaType for types like:
            <!-- Simple type list -->
            <xsd:simpleType name="LongList">
                <xsd:list>
                    <xsd:simpleType>
                        <xsd:restriction base="xsd:unsignedInt"/>
                    </xsd:simpleType>
                </xsd:list>
            </xsd:simpleType>
            <!--- Complex test type -->
            <xsd:element name="typesLongList">
                <xsd:complexType>
                    <xsd:sequence>
                        <xsd:element name="in" type="tns:LongList"/>
                    </xsd:sequence>
                </xsd:complexType>
            </xsd:element>

        Follow-up marshalling of incorrectly generated classes triggers ClassCastException at runtime:
        java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.String
