Ошибки при выполнении команды MPI_Scatter Java

Пытаюсь запустит следующий код -

import mpi.*;
import java.util.Random;
public class Main {
    public static void main(String[] args) {
        MPI.Init(args);
        int rank = MPI.COMM_WORLD.Rank();
        int size = MPI.COMM_WORLD.Size();
        int[][] sendbuf = {
                {1, 2, 3, 4},
                {1, 10, 3, 3},
                {2, 2, 2, 2},
                {1, 1, 1, 1}
        };
        int[] recvbuf = new int[4];
        if (rank == 0) {
            MPI.COMM_WORLD.Scatter(sendbuf, 4, 4, MPI.INT, recvbuf, 4, 4, MPI.INT, 0);
            System.out.println("Rank = " + rank + " Result: " + recvbuf[0] + " " + recvbuf[1] + " " + recvbuf[2] + " " + recvbuf[3]);
        }
        MPI.Finalize();
    }
}

Когда выполнение доходит до команды MPI.COMM_WORLD.Scatter выходят ошибки:
