> Please look at short reproduce:
> {code}
> import groovy.transform.TupleConstructor
> trait Some{
>     String STATIC = 'static data' // Commenting it out make it work (it have no difference static it or not)
>     String so(){
>         println ('STATIC=' + STATIC)
>     }
> }
> class Delegator implements Some{
>     String delegated(){

> s.delegated()
> {code}
> Running it I have:
