A constant field is placed beneath a non-constant field.
A violation of this rule occurs when a constant field is placed beneath a non-constant field. Constants should be placed above fields to indicate that the two are fundamentally different types of elements with different considerations for the compiler, different naming requirements, etc.
How to fix violations
To fix an instance of this violation, place all constants above all fields.
