Question

我有一些junit测试用例，我为每个测试用例创建DatagramChannelFactory。当我正常运行这些测试用例时，我在实例化NioDatagramChannelFactory 时没有任何问题。

DatagramChannelFactory channelFactory = new NioDatagramChannelFactory(Executors.newFixedThreadPool(10));

但是当我为同一段代码启用jacoco时，实例化失败了。我的jacoco与ant集成在一起，build.xml的部分内容如下所示：
由于jacoco需要fork="yes"属性，我才会添加相同的内容。

<jacoco:coverage>
  <junit printsummary="yes" haltonfailure="no" showoutput="yes" fork="yes" >
    blah.. blah.. 
    <batchtest fork="true" todir="${reportsUTrawdir}">
       blah.. blah.. 
    </batchtest>
 </junit>
</jacoco:coverage>

我的junit目标如下所示：

<junit printsummary="yes" haltonfailure="no" showoutput="yes">
  <formatter type="xml" />

  <batchtest fork="yes" todir="${reportsUTrawdir}">
    blah.. blah.. 
  </batchtest>
</junit>

我得到的堆栈跟踪是：

当我拆除我的测试用例时，我有什么遗失的东西。请帮帮我。

编辑：添加了我从junit报告中得到的原因：

启用jacoco时，新的NioDatagramChannelFactory失败
