>             Project: Groovy
>          Issue Type: Bug
>          Components: Static Type Checker
>            Reporter: Eric Milles
>            Assignee: Eric Milles
>            Priority: Major
>             Fix For: 5.0.0-alpha-1, 2.5.17, 3.0.11, 4.0.2

> Consider the following:
> {code:groovy}
> @groovy.transform.TypeChecked
> class C {
>   Map<String,Object> map
>   void test(Map<? extends String, ?> m) {
>     map.putAll(m)
>   }
> }
> {code}
> {{javac}} allows {{putAll}} in this situation.  {{groovyc}} emits an error: Cannot call {{java.util.Map#putAll(java.util.Map<? extends java.lang.String, ? extends java.lang.Object>)}} with arguments {{[java.util.Map<? extends java.lang.String, ?>]}}
