StackOverflowError在Ant中将XSD转换为Java

Question

下面是一段试图将XSD转换为Java的Ant代码：

<target name="PayAPI">
    <echo>Converting Comman API xsd to Java....</echo>
    <taskdef name="xjc" classname="com.sun.tools.xjc.XJCTask">
        <classpath>
            <fileset dir="{externalLib}" includes="*.jar" excludes="ant.jar" />
        </classpath>
    </taskdef>
    <xjc schema="${dataDir}/xsd/CommonPrefs.xsd" target="src/java/gds"
        package="com.eos.gds.webservice.CommonPrefs" extension="true" />
</target>

发生以下错误：

build.xml:1042: java.lang.StackOverflowError

    .........

在堆栈跟踪中重复出现相同的方法帧。
