ReferenceTable overflow (max=512) JNI

I am a little stuck with this one…
ReferenceTable overflow (max=512), I am sure it has to do with the Number of Local References getting created in my native method call… To work around the issue I have even tried to remove the local references from the native call; but still I am unable to solve the problem… I am passing a 2D Array; which is approaximately 1024 X 1024 …

Here is the error trace I am referring to … I am sure that number of Integer Objects getting created is causing the issue for my case … as you should be able to see 506(I) Objects are created… And then JNI hits the bottleneck…

    Here is the code I am using :
    Please let me know what is it that I am doing wrong ?

    JNIEXPORT jboolean JNICALL Java_pv_ndk_UcMobile_losInitialization
      (JNIEnv * env, jobject jobj , jint height, jint width , jobjectArray elements){
    
       elevData = new unsigned int*[height];
    
    for(i=0; i< height; i++) {
        elevData[i] = new unsigned int[width];
    
        jintArray oneDim=
        (jintArray)env->GetObjectArrayElement(
                             elements, i);
         jint *element=env->GetIntArrayElements(oneDim, 0);
         for(j=0; j< width; j++) {
             elevData[i][j]= element[j];
         }
         // This does not seem to be providing with the desired result
         // env->DeleteLocalRef(element);
    
         //I even tried with this approach
         env->ReleaseIntArrayElements(oneDim, element , 0);
    
      }
    
    return losObject.Init(elevData,1,10,2,2);
    }
