> StringUtils.rightPad(String str, int size, String padStr) throws OutOfMemoryError instead of returning the original string when size is Integer.MIN_VALUE.
>   Per the API contract, a negative size should return the original string:
>   ▎ StringUtils.rightPad("bat", -1, "yz") = "bat"
>   However, Integer.MIN_VALUE (-2147483648) is a negative value that violates this contract due to an integer overflow.
