I need to allocate rather large matrix using OpenCV 3.1.0. I'm running following code with -Djava.library.path=$MODULE_DIR$\opencv\310\windows\x64\ -Xmx8g arguments:

static { System.loadLibrary(Core.NATIVE_LIBRARY_NAME);}

@Test
public void medium() throws IOException {
    float[] data = new float[13918*13240];
    Mat iMatrix = new Mat(13918, 13240, CvType.CV_32FC1);
    iMatrix.put(0, 0, data);
}

@Test
public void tooBig() throws IOException {
    float[] data = new float[13320*67294];
    Mat iMatrix = new Mat(13320, 67294, CvType.CV_32FC1);
    iMatrix.put(0, 0, data);
}

The first test works, since the seconds throws:

java.lang.Exception: unknown exception  
at org.opencv.core.Mat.nPutF(Native Method)  
at org.opencv.core.Mat.put(Mat.java:953)

Is it a OpenCV or native library usage limitation? Is there a workaround for such issue?
