JUnit失败，但没有测试报告失败

我在Windows XP的命令行上使用Ant运行JUnit测试。JUnit失败，但没有测试报告失败

在某些运行中，通过运行所有测试，我会得到一条指向特定测试类的消息，但是该类中的所有测试都报告为已在控制台输出和XML文件。

该类不包含非确定性，不应该有任何副作用。没有理由会导致内存不足。

什么会导致这些奇怪的构建失败？

更新：

我怀疑这会有所帮助，但这里是运行结束时，它失败（匿名修改后的目录和包名）：

C:\proj\er20\rr> ant clean build test 

<snip/> 

[junit] Running com.example.PathUTest 
[junit] Tests run: 6, Failures: 0, Errors: 0, Time elapsed: 7.5 sec 

BUILD FAILED 
C:\proj\er20\common\build.xml:385: The following error occurred while executing this line: 
C:\proj\er20\rr\build.xml:58: Test com.example.PathUTest failed

更新2：

我终于设法使-verbose启用失败。这里是（手抄的）堆栈跟踪：

可能的原因和解决方法

我们发现，在内心深处在我们调用的代码中，正在显示一个在另一个线程中运行的错误调试GUI。由于禁用此GUI的显示，我们还没有看到这个问题。

后的记录错误的一大块。 – Argyle 2011-12-13 19:33:13

这些*建立*失败或*测试*失败你看到？ – 2011-12-13 19:38:05

也许在RR \ build.xml文件（你有2个生成文件）在第58行有

<fail message="Test com.example.PathUTest failed"/>
