Subject: [PATCH] Issue #1555: Mark methods as static

Fixes `MethodMayBeStatic` inspection violation.

Description:
>Reports any methods which may safely be made static. A method may be static if it is not synchronized, it does not reference any of its class' non static methods and non static fields and is not overridden in a sub class.
