jaxb - XJC 编译结果是随机的，导致不同的编组 XML

Question

随后两次使用xjc版本“2.2.3-hudson-jaxb-ri-2.2-70-”时，会产生两种不同的编译结果。问题是来自 xjc 编译结果 1 的 java 文件编组的 XML 与来自 xjc 编译结果 2 的 java 文件编组的 XML 文件不同（并且错误）。

结果 XML 的区别在于名称空间前缀 ns2 上出现/未出现：

<Activity Id="Id task1" Name="Task 1">
    <Implementation>
        <ns2:Task/>
    </Implementation>
</Activity>

负责不同结果 XML 的 java 代码的差异是 @XMLElements 中的不同顺序。
按照以下顺序，命名空间前缀出现在结果 XML 中：

@XmlElements({
@XmlElement(name = "BlockActivity", namespace = "http://www.wfmc.org/2002/XPDL1.0", type = org.wfmc._2002.xpdl1.BlockActivity.class),
@XmlElement(name = "BlockActivity", type = org.wfmc._2008.xpdl2.BlockActivity.class),

按照以下顺序，命名空间前缀不会出现在结果 XML 中：

@XmlElements({
@XmlElement(name = "BlockActivity", type = org.wfmc._2008.xpdl2.BlockActivity.class),
@XmlElement(name = "BlockActivity", namespace = "http://www.wfmc.org/2002/XPDL1.0", type = org.wfmc._2002.xpdl1.BlockActivity.class),

我编译bpmnxpdl_31.xsd

xjc.bat -verbose -no-header c:\TEMP\bpmnxpdl_31.xsd -b c:\TEMP\binding.xjb

与 binding.xjb：

有没有办法在 XJC 的后续运行中获得稳定的 @XMLElements 顺序？

我认为您可以通过指定自定义命名空间前缀映射器来解决此问题。不能解决核心问题，但可以帮助您确定命名空间。

http://java.net/jira/browse/JAXB-618 根据上面的链接，这在 2.2 分支上是固定的，但我在 2.2.5 jax-ws 下载甚至夜间构建时遇到了同样的问题.
