Array items validation is not getting picked by swagger-codegen-maven-plugin 2.4.5

[dhiraj-u-kumar]

code snippet for AddressBox array :
AddressBox:
items:
type: string
minLength: 1
maxLength: 70
type: array
description: >-
Information that locates and identifies a specific address, as defined
by postal services, presented in free format text.
minItems: 0
maxItems: 7

Here the items validation for minLength and maxLength is not picked. Although minItems and maxItems validation worked well. Can anyone guide me on the same and thanks in advance.
