ADDITIONAL SYSTEM INFORMATION :
Linux / jdk -8

A DESCRIPTION OF THE PROBLEM :
The unit test case we generated automatically failed.


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);
  }
