------------------------------
> SC: put entry replaced write field for public and protected of map-based type
> -----------------------------------------------------------------------------
>
> Key: GROOVY-11376
> URL: https://issues.apache.org/jira/browse/GROOVY-11376
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 4.0.0, 5.0.0-alpha-8
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Major
> Fix For: 5.0.0-alpha-9
>
>
> Consider the following:
> {code:groovy}
> class M implements Map<String,Object> {
> @Delegate Map<String,Object> map = [:].withDefault{ 'entry' }
> public a = 'field'
> protected b = 'field'
> @PackageScope c = 'field'
> private d = 'field'
> Closure e = { 'callable' }
> }
> @groovy.transform.CompileStatic
> void test(M map) {
> map.a = null // SC: 6549 (Groovy 4+)
> map.b = null // SC: 6549 (Groovy 4+)
> map.c = null
> map.d = null
> map.e = null
> println map // expect: [c:null, d:null]
> }
> test(new M())
> {code}
> Running this script prints "[a: null, b: null, c: null, d: null]" since
> Groovy 4. The prior behavior was to write to public and protected fields,
> which is the behavior you get if you disable static compilation.
