Maven Junit测试错误：没有字段'；分段掩码'；在类'中找到；ConcurrentHashMap'；

尝试在Maven项目中使用PowerMockRule运行Arquillian测试，以便能够模拟静态类

但是，当我构建maven项目时，我在测试中遇到以下错误：

错误测试： myTest（com.package.myTest）：无法调用java.util.concurrent.ConcurrentHashMap.readObject（）：在类“java.util.concurrent.ConcurrentHashMap”中未找到字段“segmentmask”

我不知道这是什么原因，也不知道如何着手解决。如果您有任何建议，我们将不胜感激，谢谢

编辑：显然问题是由使用PowerMockRule时需要的XStream类装入器引起的。但我还没有找到修复方法。

这确实是由x-stream问题引起的（在1.4.8中已修复）：

因此，如果您使用maven进行依赖关系管理，您可能希望在依赖关系管理中执行以下操作：

  <dependency>
    <groupId>org.powermock</groupId>
    <artifactId>powermock-classloading-xstream</artifactId>
    <version>${powermock.version}</version>
    <scope>test</scope>
    <exclusions>
      <exclusion>
        <groupId>com.thoughtworks.xstream</groupId>
        <artifactId>xstream</artifactId>
      </exclusion>
    </exclusions>
  </dependency>
  <!-- Should be removed as soon as xstream is updated in powermock -->
  <dependency>
    <groupId>com.thoughtworks.xstream</groupId>
    <artifactId>xstream</artifactId>
    <version>1.4.8</version>
    <scope>test</scope>
  </dependency>

org.powermock
powermock类加载xstream
${powermock.version}
测验
com.thoughtworks.xstream
xstream
com.thoughtworks.xstream
xstream
1.4.8
测验

然后在使用powermock的地方：

<dependency>
  <groupId>org.powermock</groupId>
  <artifactId>powermock-classloading-xstream</artifactId>
  <scope>test</scope>
</dependency>
<!-- Should be removed as soon as powermock has the latest version of xstream -->
<dependency>
  <groupId>com.thoughtworks.xstream</groupId>
  <artifactId>xstream</artifactId>
  <scope>test</scope>
</dependency>

org.powermock
powermock类加载xstream
测验
com.thoughtworks.xstream
xstream
测验

至少，在powermock开始使用新的x-stream版本之前。
