[JAVA] ISSUES GENERATING REUSABLE ENUM

Description

Hi,
If we use "reusable enum", the jaxrs-resteasy generated Server Stub produces a corrupted java enum.

Swagger-codegen version

we are using SwaggerHub with openApi 3.0.0 to design our RESTApi.

Swagger declaration file content or url

This is the yaml code definition of reusable Enum on Swagger

components:              
  schemas:
    SchedulerStatus:
      type: object
      properties:
        myEnum:
          $ref: '#/components/schemas/MyEnum'
          
    MyEnum:
      type: string
      enum:
        - "A"
        - "B"
        - "C"

And this is the generated Java Enum

public enum MyEnum {
    {values=[A, B, C], enumVars=[{name=A, value="A"}, {name=B, value="B"}, {name=C, value="C"}]}
}

This is the jaxrs-resteasy generated Server Stub project

jaxrs-resteasy-server-generated.zip

Command line used for generation

Using the Swagger Export Tool to generate the code of jaxrs-resteasy Server Stub

Steps to reproduce

. Add a reusable Enum definition to any yaml API definition
. Generate the jaxrs-resteasy server stub with the Swagger Export tool

Related issues

The issue https://github.com/swagger-api/swagger-codegen/issues/4160#issue-188059632 has my same problem, but related to JAXRS-CXF. The proposed solution doesn't work for my issue.

Suggest a fix

There is a little bug in the jaxrs-resteasy server stub codegen because, if I define the enum in the properties of an object, it's generated correctly.

Cheers, Alessandro

Start by reproducing the issue with the provided reusable-enum YAML through the Swagger Export Tool and the jaxrs-resteasy server-stub generator. Compare the generated reusable MyEnum with the correctly generated inline-property enum; done means the reusable definition produces valid Java enum source with A, B, and C values.
