Error getting values from Enum when using Groovy

[ilopmar]

Expected Behavior

When using Groovy and getting the values from an enum having an EnumElement, Micronaut should return the right values.

Actual Behaviour

Given the following Groovy Enum:

enum Type {
    DOG, CAT
}

When processing it in micronaut-openapi to get the values, Micronaut returns DOG, CAT, MIN_VALUE and MAX_VALUE and it should only return DOG and CAT.

The issues is here https://github.com/micronaut-projects/micronaut-core/blob/3.2.x/inject-groovy/src/main/groovy/io/micronaut/ast/groovy/visitor/GroovyEnumElement.java#L56-L60 but while debugging I can't find a way to differentiate those extra values from the "right" ones.

This only happens with Groovy, it works properly with Java.

Could just hard-code the exclusion for MIN_VALUE and MAX_VALUE

I though about it but it feels dirty... If there is no other way, I can do it.
