Problem unmarshalling an attribute with name "class" with Xstream

I have a node with an attribute named class. The input XML is :

<Job class="com.test.jobImplementation">
  <Priority>1</Priority>
  ......
</Job>

The Java class which represents the XML is annotated with Xstream annotations is as follows:

@XStreamAlias("Job")
public static class Job {

    @XStreamAsAttribute
    @XStreamAlias("class")
    private String implementationClass;

    @XStreamAlias("Priority")
    private Integer priority

}

When I try to deserialize the XML, xstream fails returning an error unrelated to the problem. (e.g. when I replace 开发者_如何学Gothe attribute name "class" by "classs", it works fine.)

I know the "class" attribute is used whenever XStream can't tell from the XML and the field declaration exactly what type to use, but in this case I can't modify the XML input and I have to process the attribute "class".

Any workaround for unmarshalling an XML attribute with name "class" with Xstream?

Starting with XStream 1.3.1 you can redefine those attributes to allow the names to be used for your own ones.
