[BUG] [JAVA] Default values are ignored #11459

Hi.
I'm using the latest version of the generator (5.3.1) and it seems like that default values are simply ignored when generating the model.
Given, for example, a model like

    Emails:
      type: object
      properties:
        emailAddresses:
          type: array
          default: []
          items:
            $ref: '#/components/schemas/EmailAddress'

The emailAddresses property has a value of null when the model is generated instead of an empty list.
