A DESCRIPTION OF THE PROBLEM :
We generate a unit test automatically and it failed with ArithmeticException.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
the unit test case is:
@Test
  public void test_divideUnsigned_6_119(){

      long long0 = 1L;
      long long1 = 0L;
      Long.divideUnsigned(long0, long1);

  }

ACTUAL -
java.lang.ArithmeticException: / by zero

at java.base/java.lang.Long.divideUnsigned(Long.java:1673)

---------- BEGIN SOURCE ----------
public static long divideUnsigned(long dividend, long divisor) {
        /* See Hacker's Delight (2nd ed), section 9.3 */
        if (divisor >= 0) {
            final long q = (dividend >>> 1) / divisor << 1;
            final long r = dividend - q * divisor;
            return q + ((r | ~(r - divisor)) >>> (Long.SIZE - 1));
        }
        return (dividend & ~(dividend - divisor)) >>> (Long.SIZE - 1);
    }
