Testing 使用cpsuite运行JMockit

我们在使用CPsuite和JMockit运行单元测试时遇到问题

在Eclipse中执行测试时运行良好，但如果我们使用Ant脚本运行所有测试（请参阅本问题末尾的脚本），则会出现以下异常：

Testcase: initializationError took 0 sec
    Caused an ERROR
(class: mockit/internal/startup/JDK6AgentLoader, method: getVirtualMachineImplementationFromEmbeddedOnes signature: ()Lcom/sun/tools/attach/VirtualMachine;) Wrong return type in function
java.lang.VerifyError: (class: mockit/internal/startup/JDK6AgentLoader, method: getVirtualMachineImplementationFromEmbeddedOnes signature: ()Lcom/sun/tools/attach/VirtualMachine;) Wrong return type in function

Testcase:初始化错误花费了0秒
造成错误
（类：mockit/internal/startup/JDK6AgentLoader，方法：GetVirtualMachine从EmbeddedOne实现签名：（）Lcom/sun/tools/attach/VirtualMachine；）函数中的返回类型错误
java.lang.VerifyError:（类：mockit/internal/startup/JDK6AgentLoader，方法：getVirtualMachineImplementationFromEmbeddedOnes签名：（）Lcom/sun/tools/attach/VirtualMachine；）函数中的返回类型错误

调用（Invocations.java:22）
位于java.lang.Class.forName0（本机方法）
位于java.lang.Class.forName（Class.java:169）
位于java.lang.reflect.Constructor.newInstance（Constructor.java:513）
位于java.lang.reflect.Constructor.newInstance（Constructor.java:513）

这仅在Ant上发生，并且仅当CPSuite集中存在使用JMockit的类时才会发生

有人知道我们为什么会犯这个错误吗

Ant脚本：
