[SPRING] Swagger Code Generator -3.0.11 for @baseType property

In Swagger Code Generator 3.0.11, model generation is corrected to handle the variables that start with '@' symbol . During serialization, json string contains additional attribute "atBaseType" along with "@baseType"

Json response -
{"atBaseType": "PhysicalResource",
"@baseType": "PhysicalResource"}

This can be corrected by modifying the Setter and Getter of Generated Model. Model generated with SPRING library using Swagger Code Gen 3.0.11 for @baseType property is

  @JsonProperty("@baseType")
  private String _atBaseType = null;

   public String getAtBaseType() {
    return _atBaseType;
  }

  public void setAtBaseType(String _atBaseType) {
    this._atBaseType = _atBaseType;
  }

If this is corrected to below code then additional attribute is not shown -

  public String get_atBaseType() {
    return _atBaseType;
  }

  public void set_atBaseType(String _atBaseType) {
    this._atBaseType = _atBaseType;
  }

Start with the attached yaml.zip and reproduce generation with Swagger Code Generator 3.0.11 using the Spring library. Inspect the generated model's @baseType accessors and the Spring generator templates that produce them; done means serialization contains only @baseType, not an additional atBaseType property.
