[BUG] [spring] Version 4.2.3 introduced bug in spring gen hashCode method - cannot find symbol

Description

spring-boot code generator fails in 4.2.3 with Error:(80,29) java: cannot find symbol
Here is the hashcode method generated. namesuper cannot be found.
Seems to be an issue with the template used to generate the hashcode method

  @Override
  public int hashCode() {
    return Objects.hash(id, namesuper.hashCode());
  }

I think what it is supposed to generate is:

  @Override
  public int hashCode() {
    return Objects.hash(id, name) + super.hashCode();
  }

Steps to reproduce

mvn clean compile

Reproduce the failure with the supplied OpenAPI declaration and the openapi-generator-maven-plugin configuration using mvn clean compile. Then inspect the Spring generator template responsible for the generated hashCode method; done means the generated Java code no longer references the undefined namesuper symbol and compiles successfully.
