在似乎工作了一段时间后，cloudrail 2.7.0 现在反复崩溃并出现以下问题：
Fatal Exception: java.lang.RuntimeException: ServiceCode Error in function selfTest at 26

我尝试单步执行代码，但看不到原因。我可以看到，在 InitSelfTest 中，以下行未包含在 try/catch 块中，因此可能假设 appContext.getPackageName() 不为空？
ip.callFunction("selfTest", new Object[]{interpreterStorage, appContext.getPackageName(), appInfo1.className, appVersionName, appVersionCode});
