      I think the problem lies in a circular hashCode generation between 

      org.onap.vid.model.CategoryParameter.hashCode(CategoryParameter.java:118)org.onap.vid.model.CategoryParameter.hashCode(CategoryParameter.java:118) org.onap.vid.model.CategoryParameterOption.hashCode(CategoryParameterOption.java:141)

       

      @Override
      public int hashCode()

      { return Objects.hash(this.name, this.idSupported, this.family, this.options); }

      &

      @Override
      public int hashCode()

      { int result = getAppId() != null ? getAppId().hashCode() : 0; result = 31 * result + (getName() != null ? getName().hashCode() : 0); result = 31 * result + (getCategoryParameter() != null ? getCategoryParameter().hashCode() : 0); return result; }
