When program use Interrupt handler on BeagleBoardBlack native code exception is occured

Java program: String pinName = args[0]; Board board = Platform.createBoard(); DigitalInput isClose = board.getPin(pinName).as(DigitalInput.class);

    Button button = new Button(isClose, io.silverspoon.bulldog.core.Signal.Low);
    button.addListener(new ButtonListener() {

        @Override
        public void buttonPressed() {
            System.out.println("PRESSED");
        }

        @Override
        public void buttonReleased() {
            System.out.println("RELEASED");
        }
    });

    for(int i=0; i<100; i++){
        System.out.println(isClose.read().getNumericValue());
        Thread.sleep(300);
    }

    Thread.sleep(20000);
    System.out.println("DONE");

Hello all, I faced the same issue on my Beaglebone black and found a workaround, so I would like to let you know of my findings. Versions of my software: uname -a Linux alarm 4.8.5-1-ARCH #1 Sat Oct 29 20:34:37 MDT 2016 armv7l GNU/Linux

java -version openjdk version "1.8.0_112" OpenJDK Runtime Environment (build 1.8.0_112-b15) OpenJDK Zero VM (build 25.112-b15, interpreted mode)

So, at the beggining I was using crosscompiled version of Bulldog from my desktop PC (arm gcc 6.1.1) and I was facing similar errors when attaching interrupt listeners to Input GPIOS. From what I saw, the problems came from Bulldog natives. Afterwards I tried and recompiled Bulldog on the Beaglebone itself (gcc 6.2.1) and the problem went away. Could it be that there is some mismatch in headers? I hope this could point you out to successfull solution. Have a nice days. Jan
