在Eclipse Android项目中无法运行JUnit 4测试用例

我是Java新手，正在尝试对正在编写的类进行单元测试。Eclipse（3.5）为我创建了单元测试类，并将Junit4添加到了我的类路径中。

我的课：

public class DistanceUtil 
{

public static double metersToMiles( double meters ) 
{
    return 0;
}
public static double metersToKilometers( double meters ) 
{
    return 0;
}

}

我的单元测试：

public class DistanceUtilTest {

@Test
public final void testMetersToMiles() {
    fail("Not yet implemented"); // TODO
}

@Test
public final void testMetersToKilometers() {
    fail("Not yet implemented"); // TODO
}

}

当我右键单击单元测试并选择以Junit Test运行时，我得到以下信息：

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error (classFileParser.cpp:3075), pid=5564, tid=4940
#  Error: ShouldNotReachHere()

# JRE version: 6.0_17-b04

# An error report file with more information is saved as:

有人知道我该如何解决吗？

谢谢
