MOXy - 使用自包含类引导JAXBContext时的StackOverflowError [英] MOXy - StackOverflowError when bootstrapping JAXBContext with a self-containing class

问题描述

我正在尝试使用EclipseLink MOXy JAXB实现来解组一些XML数据。我有以下带注释的类，它有自己类型的成员：

I'm trying to use the EclipseLink MOXy JAXB implementation to umarshal some XML data. I have the following annotated class, which has a member of its own type:

package stackoverflow.q19191209;

import javax.xml.bind.annotation.*;

@XmlRootElement(name="Item")
public class Item
{
    @XmlAttribute(name="name")
    @XmlID
    private String m_name;

    @XmlAttribute(name="parent")
    @XmlIDREF 
    private Item m_parent;
}

此类列在jaxb.in​​dex中。当我尝试引导我的JAXBContext时：

This class is listed in jaxb.index. When I attempt to bootstrap my JAXBContext:

JAXBContext context = JAXBContext.newInstance("stackoverflow.q19191209");       

它会挂起一秒钟，然后给我一个StackOverflowError：

it hangs for a second, and then gives me a StackOverflowError:

Exception in thread "main" java.lang.StackOverflowError
    at java.util.HashMap$ValueIterator.<init>(HashMap.java:820)
    at java.util.HashMap$ValueIterator.<init>(HashMap.java:820)
    at java.util.HashMap.newValueIterator(HashMap.java:843)
    at java.util.HashMap$Values.iterator(HashMap.java:910)
    at org.eclipse.persistence.jaxb.compiler.AnnotationsProcessor.hasTextMapping(AnnotationsProcessor.java:3998)
    at org.eclipse.persistence.jaxb.compiler.AnnotationsProcessor.hasTextMapping(AnnotationsProcessor.java:4003)
    at org.eclipse.persistence.jaxb.compiler.AnnotationsProcessor.hasTextMapping(AnnotationsProcessor.java:4003)
...

当我使用默认的JAXB提供程序时，它不会发生 - 它正确地解组，并且所有关系都已正确建立。这是一个MOXy错误吗？

This does not happen when I use the default JAXB provider - it unmarshals correctly, and all relationships are correctly established. Is this a MOXy bug?

我尝试过JDK 1.6.0_25和JDK 1.7.0_21，以及MOXy版本2.5.0,2.5.1和2.6.0 - 结果相同。

I've tried JDK 1.6.0_25 and JDK 1.7.0_21, and MOXy versions 2.5.0, 2.5.1, and 2.6.0 - same results.

谢谢！
