jaxb - getting InvocationTargetException during parsing

Hi all,
I'm trying to get JAXB to generate the java classes by using xjc.sh on test.xsd (shown below). Apparently, JAXB does not like it when i try to use extension on a complexType/simpleContent/Restriction? Is there something i'm doing wrong or does xjc.sh not support what i'm trying to do? Would appreciate any help/hints. Thanks!
I am using jwsdp-1.3 and j2sdk1.4.1_02.
I've tried the following command line invocations:
xjc.sh -p <package name> -d <working dir> test.xsd
xjc.sh -p <package name> test.xsd
xjc.sh test.xsd

----- test.xsd -----
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="http/www/test"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:se="http/www/test" elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xs:element name="Root" type="se:CSEonCSR">
<xs:annotation>
<xs ocumentation>Root element</xs ocumentation>
</xs:annotation>
</xs:element>
<!-- this guy is the culprit..causes error with either simpleContent or complexContent -->
<xs:complexType name="CSEonCSR">
<xs:simpleContent>
<xs:extension base="se:CSRonCSE"/>
</xs:simpleContent>
</xs:complexType>
<!-- this is the guy that CSEonCSR cannot use extension on -->
<xs:complexType name="CSRonCSE">
<xs:simpleContent>
<xs:restriction base="se:CSE">
<xs:minLength value="1"/>
<xs:maxLength value="60"/>
</xs:restriction>
</xs:simpleContent>
</xs:complexType>
<xs:complexType name="CSE">
<xs:simpleContent>
<xs:extension base="xs:string"/>
</xs:simpleContent>
</xs:complexType>
</xs:schema>
