问使用JNI调用本机(C++)函数的访问冲突:这是我的代码中的问题还是已知的问题？

EN

// C++ declaration/definition of the native function:

JNIEXPORT void JNICALL setEncoderProgressStatus (JNIEnv * env, jobject theClass, jlong jEncoderDecoderDlg, jstring status)
{
    // Do nothing.  Obviously, the real function does something.
    // But an access violation is reported even in the do-nothing case.
}

// Registration of this function with JNI in the C++ code

JNINativeMethod commandLineEncoderMethods[] =
{
    {"setEncoderProgressStatus","(JLjava/lang/String;)V", (void*)setEncoderProgressStatus}
};

// pEnv is a valid JNIEnv *
// jCommandLineEncoderClass has already been initialized
pEnv->RegisterNatives(jCommandLineEncoderClass, commandLineEncoderMethods, sizeof(commandLineEncoderMethods)/sizeof(JNINativeMethod))

// The Java code, in turn, declares the native function as follows:

public static native void setEncoderProgressStatus(long EncoderDecoderDlg, String status);

// Finally, the Java code calls the native function as follows:

// The real code passes different args,
// but an access violation is reported even in the do-nothing case.
// Commenting out the following line of code makes the access violation disappear.

setEncoderProgressStatus(0, "");
