问题描述
docx4j（我主持）通常与Sun / Oracle JAXB实现一起使用;下面感兴趣的类是使用XJC生成的。
docx4j (which I host) is typically used with the Sun/Oracle JAXB implementation; the classes of interest below were generated using XJC.
我以为我会尝试EclipseLink MOXy，看看它是怎么回事。
I thought I'd try EclipseLink MOXy, to see how it went.
在上下文初始化时，我收到以下错误：
On context init, I get the following error:
ERROR org.docx4j.jaxb.Context .<clinit> line 107 - Cannot initialize context
javax.xml.bind.JAXBException:

第一个一对引用的类，我们有一个枚举和
The first pair of referenced classes, we have an enum STCF and CTClientData
第二对引用类，我们有另一个枚举和
The second pair of referenced classes, we have another enum STSourceType and CTSourceType
我该如何解决这个问题？
How might I workaround this problem?
