From: =?UTF-8?q?=E7=94=B0=E6=AC=A7?= <thinkerou@gmail.com>

Subject: [PATCH] use checkPositive/checkPositiveOrZero (#8835)
Motivation:
We can replace some "hand-rolled" integer checks with our own static utility method to simplify the code.
Modifications:
Use methods provided by `ObjectUtil`.
Result:
Cleaner code and less duplication
