Description

class Reproducer {
    public static final Map<Role, String> ROLE_MAPPING = EnumMap.of(Role.A, 'a')
    //     public static final Map<Role, String> ROLE_MAPPING = EnumMap.of(Role.A, 'a', Role.B, 'b', Role.C, 'c', Role.D, 'd')
    
    static void main(String... args) {
        println ROLE_MAPPING
    }
}

enum Role {
    A, B, C, D
}

(Groovy Web Console)

Works fine in Groovy 2.5 and 3.x but fails with Groovy 4.
