在android中调用jni,出现ReferenceTable overflow (max=1024)

小弟最近入手android的jni，大体是做个车牌识别的功能，但在java层循环调用jni识别算法时出现了ReferenceTable overflow (max=1024)这个错误，程序整个就退出了，到网上查了是说没有释放资源，但也不是这么回事，小弟无计可施了，恳请各位帮忙，不胜感激！代码&日志如下，
代码：
extern "C" JNIEXPORT jdouble JNICALL Java_com_opencv_lpr_LibLPR_LPRprocess(
JNIEnv* env, jobject obj, jintArray imgbuf, jint w, jint h, jintArray scanArea, jlongArray BPaddress, jintArray result)
{
jint *cimgbuf = env->GetIntArrayElements(imgbuf, 0);
jint *cscanArea = env->GetIntArrayElements(scanArea, 0);
jlong *cBPaddress = env->GetLongArrayElements(BPaddress, 0);
jint *cresult = env->GetIntArrayElements(result, 0);

... env->ReleaseIntArrayElements(result, cresult, 0);
env->ReleaseLongArrayElements(BPaddress, cBPaddress, 0);
env->ReleaseIntArrayElements(scanArea, cscanArea, 0);
env->ReleaseIntArrayElements(imgbuf, cimgbuf, 0);

return ...
}日志如下：
