（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, );
     char* pApath=env->GetStringUTFChars(path,);
     jint* pAx1 = (jint*)env->GetPrimitiveArrayCritical(x1, );

     // code;

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

     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, );
     jint* pAx1 = (jint*)env->GetPrimitiveArrayCritical(x1, );
     char* pApath=env->GetStringUTFChars(path,);

     // code;

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

     return eyedist;
 }
