Bug description

Given the following components:

components:
  schemas:
    PatchRequest:
          type: array
          items:
            oneOf:
              - $ref: '#/components/schemas/JSONPatchRequestAddReplaceTest'
              - $ref: '#/components/schemas/JSONPatchRequestRemove'
              - $ref: '#/components/schemas/JSONPatchRequestMoveCopy'


    JSONPatchRequestAddReplaceTest:
      type: object
      additionalProperties: false
      ...
    JSONPatchRequestRemove:
      type: object
      ...   
    JSONPatchRequestMoveCopy:
      type: object
      additionalProperties: false

And given the usage of the following configuration setting in the Maven plugin:

<additionalModelTypeAnnotations>@lombok.Builder @lombok.NoArgsConstructor @lombok.AllArgsConstructor</additionalModelTypeAnnotations>

The plugin generates an Java Interface annotated with Lombok annotations:

lombok.Builder @lombok.NoArgsConstructor @lombok.AllArgsConstructor

@Generated(value = "org.openapitools.codegen.languages.SpringCodegen", date = "2022-11-04T13:47:46.119673+01:00[Europe/Berlin]")
public interface PatchRequestInner extends Serializable {
}

This makes the compilation to fail.
