(was: I have checked with "org.apache.commons.lang3.StringUtils" class for the equals method. It produces wrong results.
please find the logic which is present in the "org.apache.commons.lang3.StringUtils" class and try it.

package org.apache.commons.lang3;
 public static boolean equals(CharSequence cs1, CharSequence cs2)
  {
    return cs1 == null ? false : cs2 == null ? true : cs1.equals(cs2);
  }

If cs2 is null, the above logic returns "true", that means it doesn't produce correct result.)

> When we use StringUtils equals() method with below scenario, it returns wrong results.
> Scenario : StringUtils.equals("someStr", null);
> Result : true
> Expected result : false
> Explanation:
> Some logical / typo mistake on the below line.
> return ((str1 == null) ? false : (str2 == null) ? true : str1.equals(str2));
> Instead of "true" it should be "false", when str2 is checked.
