Paul King closed GROOVY-11368.
------------------------------
> SC: map access different for parameter and local variable of same type
> ----------------------------------------------------------------------
>
> Key: GROOVY-11368
> URL: https://issues.apache.org/jira/browse/GROOVY-11368
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 3.0.21, 4.0.21
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Major
> Fix For: 3.0.22, 4.0.22
>
>
> Consider the following:
> {code:groovy}
> class C implements Map<String,String> {
> @Delegate Map<String,String> impl = [:]
> }
> def map = new C()
> assert map.entry == null
> assert map.empty == null
> assert map.class == null
> assert map.metaClass == null
> def test(C map) {
> assert map.entry == null
> assert map.empty == null
> assert map.class == null
> assert map.metaClass == null
> }
> test(new C())
> {code}
> The method-based test fails with "class" returning the map class. Something
> is different for local variable and parameter property expressions.
