>                 Key: GROOVY-11369
>                 URL: https://issues.apache.org/jira/browse/GROOVY-11369
>             Project: Groovy
>          Issue Type: Bug
>          Components: Static Type Checker
>    Affects Versions: 3.0.21, 4.0.21
>            Reporter: Eric Milles
>            Assignee: Eric Milles
>            Priority: Major
>             Fix For: 3.0.22, 5.0.0-alpha-9, 4.0.22

> Consider the following:
> {code:groovy}
> @TypeChecked test(Map map) {
>   print map.empty
>   print map.class
>   print map.metaClass
>   map.empty = null
>   map.class = null
>   map.metaClass = null
>   print map
> }
> test([:])
> {code}
> When executed (without {{{}@TypeChecked{}}}) the script prints "null", "null", "null", "[empty: null, class: null, metaClass: null]". So these are all map entry read and writes. However, STC indicates that "class" and "empty" are read-only properties.
