Question

我正在尝试编写一个在java中使用的本机方法，用于速度目的，但它不起作用。它编译好，但有时它绝对没有，有时它会这样说：

`Execution protection violation
#
# A fatal error has been detected by the Java Runtime Environment:
#
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x00009f0a, pid=8768,  tid=8780
#
# JRE version: Java(TM) SE Runtime Environment (8.0_05-b13) (build 1.8.0_05- b13)
# Java VM: Java HotSpot(TM) Client VM (25.5-b02 mixed mode windows-x86 )
# Problematic frame:
# C  0x00009f0a
#
# Failed to write core dump. Minidumps are not enabled by default on client  versions of Windows

#`

这是本机方法声明：
public static native byte[][][] createArray();

这是.cpp文件：

#include <jni.h>
#include "NativeTest.h"

JNIEXPORT jobjectArray JNICALL 
    Java_NativeTest_createArray(JNIEnv *env, jclass cls){
        printf("Native method running");
        jobjectArray joa;
        jbyteArray jba;
        jclass joaCls = env->GetObjectClass(joa);
        jclass jbaCls = env->GetObjectClass(jba); 
        return (*env).NewObjectArray(20, joaCls, (*env).NewObjectArray(20, jbaCls, (*env).NewByteArray(3)));
}

int main(){
}

如果你想看到其他任何东西，我可以发布它。错误日志对我没有任何帮助，但也许其他人可以破译它。我听说这些错误通常是由于非法的阵列/内存访问造成的;你不能像那样初始化jarray吗？
