jni代碼中的FindClass崩潰JVM

我想從C++代碼編寫一個相當基本的JNI調用。jni代碼中的FindClass崩潰JVM

JavaVM *jvm; 
JNIEnv *env; 
JavaVMInitArgs vm_args; 
JavaVMOption options[2]; 

// Get the default initialization arguments and set the class 
// path. 
JNI_GetDefaultJavaVMInitArgs(&vm_args); 
options[0].optionString = "-Djava.class.path=./hbase-1.0-SNAPSHOT.jar" 
options[1].optionString = "-verbose:jni"; 
vm_args.nOptions = 2; 
vm_args.version = JNI_VERSION_1_6; 
vm_args.options = options; 


// Load and initialize a Java VM, return a JNI interface 
// pointer in env. 
long result = JNI_CreateJavaVM(&jvm, (void **)&env, &vm_args); 
if (result == JNI_ERR) { 
    LOG(ERROR) << "Failed to create a JVM"; 
    return false; 
} 

jclass cls = env->FindClass("com/scaligent/falcon/hbase/HFileJniReader");

我的代碼在FindClass中崩潰。奇怪的是，我在類中有一個靜態塊，它將消息打印在靜態塊中。我在這裏發佈了幾行錯誤。我無法弄清楚如何調試或解決這個問題。

你是否找到了解決方案？ – peeyush

它似乎jni拋出通常它會捕獲的信號，但在gdb中，它會導致gdb報告崩潰。我的代碼有其他的錯誤，我無法捕捉，因爲我依靠gdb進行調試。 –

@amit：做你的C++可執行文件使用jar也可以在你的java代碼庫中使用其他第三方jar或其他依賴jar，然後你需要指定那裏的路徑，因爲你的規範我只能找到這個問題。 – user1808932
