Enum list issue

[sebplorenz]

Hi,
there seems to be an issue when generating an enum that is a used in a list property of an object.

The following spec:

openapi: 3.0.2
info:
  title: Test Spec
  version: '0'
  
paths: { }

components:
  schemas:
    Person:
      type: object
      properties:
        mood:
          type: array
          items:
            type: string
            enum:
              - HAPPY
              - CREATIVE
              - CHALLANGED
              - WORRIED
              - SUICIDAL

generates this enum:

public enum Mood {

	HAPPY("HAPPY"),
	CREATIVE("CREATIVE"),
	CHALLANGED("CHALLANGED"),
	WORRIED("WORRIED"),
	SUICIDAL("SUICIDAL");

	public static final java.util.List<java.lang.String> HAPPY_VALUE = "HAPPY";
	public static final java.util.List<java.lang.String> CREATIVE_VALUE = "CREATIVE";
	public static final java.util.List<java.lang.String> CHALLANGED_VALUE = "CHALLANGED";
	public static final java.util.List<java.lang.String> WORRIED_VALUE = "WORRIED";
	public static final java.util.List<java.lang.String> SUICIDAL_VALUE = "SUICIDAL";

	private final java.util.List<java.lang.String> value;

	private Mood(java.util.List<java.lang.String> value) {
		this.value = value;
	}

	@com.fasterxml.jackson.annotation.JsonCreator
	public static Mood toEnum(java.util.List<java.lang.String> value) {
		return toOptional(value).orElseThrow(() -> new IllegalArgumentException("Unknown value '" + value + "'."));
	}

	public static java.util.Optional<Mood> toOptional(java.util.List&lt;java.lang.String&gt; value) {
		return java.util.Arrays
				.stream(values())
				.filter(e -> e.value.equals(value))
				.findAny();
	}

	@com.fasterxml.jackson.annotation.JsonValue
	public java.util.List&lt;java.lang.String&gt; getValue() {
		return value;
	}
}
