（原）不明白JNI指针调用顺序

很不明白JNI里面获取指针的顺序（可能这样描述不太恰当吧）。

下面按照传入指针的顺序的代码一跑就崩溃。如下：

JNIEXPORT jint JNICALL Java_com_example_X_XX_XXX
  (JNIEnv * env, jclass, jbyteArray databuf, jint width, jint height, jstring path, jintArray x1)
{
    jboolean* pArraydata = (jboolean*)env->GetPrimitiveArrayCritical(databuf, 0);
    char* pApath=env->GetStringUTFChars(path,0);
    jint* pAx1 = (jint*)env->GetPrimitiveArrayCritical(x1, 0);

    // code;

    env->ReleasePrimitiveArrayCritical(databuf, pArraydata, 0);
    env->ReleaseStringUTFChars(path, pApath);
    env->ReleasePrimitiveArrayCritical(x1, pAx1, 0);

    return eyedist;
}

之后将获取指针的顺序稍微修改了一下，然后就可以跑过去了。如下：

JNIEXPORT jint JNICALL Java_com_example_X_XX_XXX
  (JNIEnv * env, jclass, jbyteArray databuf, jint width, jint height, jstring path, jintArray x1)
{
    jboolean* pArraydata = (jboolean*)env->GetPrimitiveArrayCritical(databuf, 0);
    jint* pAx1 = (jint*)env->GetPrimitiveArrayCritical(x1, 0);
    char* pApath=env->GetStringUTFChars(path,0);

    // code;

    env->ReleasePrimitiveArrayCritical(databuf, pArraydata, 0);
    env->ReleasePrimitiveArrayCritical(x1, pAx1, 0);
    env->ReleaseStringUTFChars(path, pApath);

    return eyedist;
}
