How to use OpenCV 4 in Java on Raspberry PI (armv6 and armv7 Raspian)?

edit

Please note this is a cross-post also present on stackoverflow, but I would also like the expertise of this wonderful expert community.

This question is very similar to this one however it's on Linux ARM ( Raspberry Pi).

I've compiled OpenCV 4.4.0 from source along with the Java bindings and tried something like this hack (that worked on Windows):

import org.opencv.core.*;

public class CVTest {

        public static void main(String[] args) {
                System.out.println("setup");
//              loading the typical way fails :(
//              System.loadLibrary(Core.NATIVE_LIBRARY_NAME);

                System.load("/home/pi/eclipse/CVTest/lib/libopencv_core.so");
////System.load("/home/pi/opencv/build/lib/libopencv_core.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_imgproc.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_imgcodecs.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_img_hash.so");
////System.load("/home/pi/eclipse/CVTest/lib/opencv_core.so");//videoio_ffmpeg440_64.dll
//System.load("/home/pi/eclipse/CVTest/lib/libopencv_videoio.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_photo.so");

System.load("/home/pi/eclipse/CVTest/lib/libopencv_xphoto.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_flann.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_features2d.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_calib3d.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_phase_unwrapping.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_structured_light.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_xfeatures2d.so");

System.load("/home/pi/eclipse/CVTest/lib/libopencv_video.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_ximgproc.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_aruco.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_bgsegm.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_bioinspired.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_objdetect.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_face.so");

System.load("/home/pi/eclipse/CVTest/lib/libopencv_tracking.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_plot.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_ml.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_ml.so");
System.load("/home/pi/eclipse/CVTest/lib/libopencv_text.so");
// crashes here!
System.load("/home/pi/eclipse/CVTest/lib/libopencv_java440.so");


Mat m = Mat.eye(new Size(3,3), CvType.CV_8UC1);
                System.out.println("done");
        }

}

However, depending on the Raspberry Pi, I get different crashes at the same line, loading libopencv_java440 (after the other dependant libraries have loaded):

On a Raspberry Pi 3B running Raspian stretch I get errors like this one:
