JNI传递对象数组问题！！

Question

jclass clsList = env->FindClass("java/util/ArrayList");
jclass clsCruiseInfo = env->FindClass("com/uniview/netsdk/Bean/CruiseInfoBean");
jclass clsCruisePoint = env->FindClass("com/uniview/netsdk/Bean/CruisePointBean");
jmethodID mtdListInit = env->GetMethodID(clsList, "", "()V");
jmethodID mtdListAdd = env->GetMethodID(clsList, "add", "(Ljava/lang/Object;)Z");
jmethodID mtdCuriseInit = env->GetMethodID(clsCruiseInfo, "", "()V");
jmethodID mtdCuriseID = env->GetMethodID(clsCruiseInfo, "setDwCuriseID", "(I)V");
jmethodID mtdCuriseName = env->GetMethodID(clsCruiseInfo, "setSzCuriseName", "(Ljava/lang/String;)V");
jmethodID mtdSize = env->GetMethodID(clsCruiseInfo, "setDwSize", "(I)V");
jmethodID mtdCruisePoint = env->GetMethodID(clsCruiseInfo, "setAstCruisePoint", "([Lcom/uniview/netsdk/Bean/CruisePointBean;)V");
jmethodID mtdCruisePointInit = env->GetMethodID(clsCruisePoint, "", "()V");
jmethodID mtdPresetID = env->GetMethodID(clsCruisePoint, "setDwPresetID", "(I)V");
jmethodID mtdStayTime = env->GetMethodID(clsCruisePoint, "setDwStayTime", "(I)V");
jmethodID mtdSpeed = env->GetMethodID(clsCruisePoint, "setDwSpeed", "(I)V");
jmethodID mtdReserve = env->GetMethodID(clsCruisePoint, "setDwReserve", "(I)V");
jsize len1 = stCuriseList.dwSize;
for(int i = 0; i < len1; i++)

{
jobject objCruiseInfo = env->NewObject(clsCruiseInfo, mtdCuriseInit, "");
env->CallVoidMethod(objCruiseInfo, mtdCuriseID, (jint)stCuriseList.astCruiseInfo[i].dwCuriseID);
env->CallVoidMethod(objCruiseInfo, mtdCuriseName, env->NewStringUTF(stCuriseList.astCruiseInfo[i].szCuriseName));
env->CallVoidMethod(objCruiseInfo, mtdSize, (jint)stCuriseList.astCruiseInfo[i].dwSize);
jsize len2 = stCuriseList.astCruiseInfo[i].dwSize;
printf("1\n");
jobject arrayCount = env->AllocObject(clsCruiseInfo);

for(int k = 0; k < len2; k++)

{
jobject objobjCruisePoint = env->NewObject(clsCruisePoint, mtdCruisePointInit, "");
env->CallVoidMethod(objobjCruisePoint, mtdPresetID, (jint)stCuriseList.astCruiseInfo[i].astCruisePoint[k].dwPresetID);
env->CallVoidMethod(objobjCruisePoint, mtdStayTime, (jint)stCuriseList.astCruiseInfo[i].astCruisePoint[k].dwStayTime);
env->CallVoidMethod(objobjCruisePoint, mtdSpeed, (jint)stCuriseList.astCruiseInfo[i].astCruisePoint[k].dwSpeed);
env->CallVoidMethod(objobjCruisePoint, mtdReserve, (jint)stCuriseList.astCruiseInfo[i].astCruisePoint[k].dwReserve);
env->CallBooleanMethod(arrayCount, mtdListAdd, objobjCruisePoint);
}

        env->CallObjectMethod(objCruiseInfo, mtdCruisePoint, arrayCount);

        env->CallBooleanMethod(pstCruiseList, mtdListAdd, objCruiseInfo);

在倒数第二行报错，请大神解答！
