As you can see returnSoftwareStatus is supposed to be of type DeviceLifecycleStatus. If you look in the generated code, you will see that it is of type DeviceLifecycleStatusCore instead:

public DeviceLifecycleCore returnSoftwareStatus(DeviceLifecycleStatusCore returnSoftwareStatus) {
    this.returnSoftwareStatus = returnSoftwareStatus;
    return this;
  }

   /**
   * DeviceLifecycleStatus
   * @return returnSoftwareStatus
  **/
  @Valid
  public DeviceLifecycleStatusCore getReturnSoftwareStatus() {
    return returnSoftwareStatus;
  }

  public void setReturnSoftwareStatus(DeviceLifecycleStatusCore returnSoftwareStatus) {
    this.returnSoftwareStatus = returnSoftwareStatus;
  }

Command line used for generation

java -jar openapi-generator-cli.jar generate -i ./swagger.yaml --generator-name java-play-framework -o generatedServer -DhideGenerationTimestamp=true,booleanGetterPrefix=is

Steps to reproduce
