在使用Play Framework v1和IntelliJ 13 CE并运行jUnit测试时，我在启动时收到UnExpectedException

Question

过去两周我一直在使用IntelliJ CE，突然之间我遇到了在IntelliJ中运行单元测试的问题。我的团队使用Play Framework v1.2.5，如果我从命令行运行项目，它编译并运行正常。如果我在Eclipse Kepler中运行项目测试，它们可以正常工作。只有当我在IntelliJ中运行测试时，我才会在启动时收到此异常：

该课程在项目中，但未经过测试。我试过：

1. 播放干净（删除播放缓存）
2. 播放idealize（重新生成IntelliJ项目，重新导入）
3. 播放eclipsify（重新生成eclipse项目，然后导入IntelliJ）
4. 从IntelliJ，File |中使缓存无效并重新启动
5. 将我的JDK从1.7.0_45升级到1.7.0_51
6. 升级至IntelliJ CE 13.1
7. 克隆回购的新副本，重新导入

我在Mac上，如果这有任何区别。还有其他人经历过吗？有什么建议可以尝试吗？

编辑：我的Linux开发机器上存在同样的问题。

我相信我找到了解决方案。 PlayFramework v1与Java 7的验证程序有一些问题。

将-XX：-UseSplitVerifier添加到jUnit Run / Debug配置解决了这个问题。
