Code runs in infinite loop if base type of complex type is simple

[dhumeniuk]

In XSDParser.parseComplexType():

At some point parent will be simple type so the loop just runs forever.

       while (parent != sset.getAnyType()) {
            if (parent.isComplexType()) {
                write(st, parent.asComplexType(), true, sset);
                parent = parent.getBaseType();
            }
        }

Here is an example schema on which xsd2thrift gets stuck.
Jeff Murphy's clone seems to be on the way to fixing this.

<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:complexType name="MultilingualString">
        <xs:sequence>
            <xs:element name="value" type="MultilingualStringValue" maxOccurs="unbounded"/>
        </xs:sequence>
    </xs:complexType>
    <xs:simpleType name="MultilingualStringValueType">
        <xs:restriction base="xs:string">
            <xs:maxLength value="1024"/>
        </xs:restriction>
    </xs:simpleType>
    <xs:complexType name="MultilingualStringValue">
        <xs:simpleContent>
            <xs:extension base="MultilingualStringValueType">
                <xs:attribute name="lang" type="xs:language"/>
            </xs:extension>
        </xs:simpleContent>
    </xs:complexType>
</xs:schema>

True, it gets into an infinite loop. Do you know how far jeffmurphy's fork has gotten so far?

This is the protobuf output on the above xml using @jeffmurphy's fork from March 1st:

message MultilingualStringValue
{
    optional string lang = 1;
}

message MultilingualString
{
    repeated MultilingualStringValue value = 1;
}

The simpleType seems to get completely ignored, but at least it doesn't get stuck.
