      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      The unit test case is :
        @Test
        public void test_resize_1_1() {
            long long2 = 4537745743783926328L;
            long long3 = -1L;
            BitVector bitVector0 = new BitVector(long3);
            bitVector0.resize(long2);
        }
