---------------------------------------------------------------
If your use case is to create an {{EnumSet}} of all of the enum constants, you
can use {{EnumSet.allOf(Test1)}} to do that.
The runtime matches 3 candidate methods under Java 11:
{code:java}
Set Set.of(Object...)
Set Set.of(Object, Object, Object, Object, Object, Object)
EnumSet EnumSet.of(Enum, Enum...)
{code}
The middle one matches based on the return values of
{{MetaClassHelper#calculateParameterDistance}}.

> Key: GROOVY-11107
> URL: https://issues.apache.org/jira/browse/GROOVY-11107
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.5.22, 3.0.17
> Reporter: Anton Panikov
> Priority: Major
>
> EnumSet.of() has 6 overloaded variants, the one with varargs is throwing
> GroovyRuntimeException, claiming it can not find a proper constructor. But it
> is working for jdk 8 with any Groovy version: 2.4, 2.5, 3.0 and 4.0, broken
> for jdk 11 and 17 with 2.5 and 3.0 and working fine for groovy 4.0 with any
> jdk.
> It is a runtime exception and the code needs to access the field:
>
> {code:java}
> package test
> enum Test1 {
> ONE,
> TWO,
> THREE,
> FOUR,
> FIVE,
> SIX
>
> public static EnumSet<Test1> test1 = EnumSet.of(ONE, TWO, THREE, FOUR,
> FIVE, SIX)
> //public static EnumSet<Test1> test2 = EnumSet.of(ONE, TWO, THREE, FOUR)
> + EnumSet.of(FIVE, SIX) // workaround to not use varargs, works for any
> combinations
> }
> class Application {
> static void main(String[] args) {
> Test1.test1
> }
> }
> {code}
> It was working fine in groovy 2.4 and all groovy version using jdk 8. But in
> groovy 2.5 and 3.0, using JDK 11 and 17 it is throwing an exception:
