Remove final qualifiers Final qualifier in private methods are redundant as per JLS: "A private method and all methods declared immediately within a final class (ยง8.1.1.2) behave as if they are final, since it is impossible to override them." Also remove final qualifier from method parameters according to Gerrit code style guide [1].
