[Java] overridden enums in allOf cause compilation failure

[frantuma]

In a scenario like, with latest 3.0.14-SNAPSHOT :

openapi: 3.0.0
info:
  version: 1.0.0
  title: Enums
paths: {}
components:
  schemas:
    Child:
      allOf:
        - $ref: '#/components/schemas/Parent'
        - type: object
          properties:
            foo:
              type: string
              enum:
                - bar
    Parent:
      type: object
      properties:
        id:
          type: string
        foo:
          type: string
          description: 'this property will be the one used'
          enum:
            - bar
            - foo

a generated java code doesn't compile as two different enums are used in generated Parent and Child pojos, with same accessors and name.
