>             Project: Groovy
>          Issue Type: Bug
>          Components: Static compilation
>    Affects Versions: 3.0.0-alpha-2, 2.4.15, 2.5.0
>         Environment: Elementary OS Freya 0.3.2
> java version "1.8.0_121"

> I'm trying to use Groovy's short hand way to put a new key value to an encapsulated Map. But the compilation fails with:
>  
> {code:java}
> [Static type checking] - Cannot assign value of type java.lang.String to variable of type ?   
> {code}
>  
> Scenario to reproduce:
> {code:java}
> import groovy.transform.CompileStatic
> @CompileStatic
> class MapHolder {
>    private Map<?, ?> map = [:]
>    Map<?, ?> getMap() {
>       return map
>    }
> }
> @CompileStatic
> static setMapValue() {
>    MapHolder mapHolder = new MapHolder()
>    mapHolder.map.key = 'value'
> }
> setMapValue()
> {code}
> Using the *put* method works just fine:
> {code:java}
> import groovy.transform.CompileStatic
> @CompileStatic
> class MapHolder {
>    private Map<?, ?> map = [:]
>    Map<?, ?> getMap() {
>       return map
>    }
> }
> @CompileStatic
> static setMapValue() {
>    MapHolder mapHolder = new MapHolder()
>    mapHolder.put('key', 'value')
> }
> setMapValue()
> {code}
>
