> STC: inferred type of this.name within closure
> ----------------------------------------------
>
> Key: GROOVY-11402
> URL: https://issues.apache.org/jira/browse/GROOVY-11402
> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Affects Versions: 3.0.21, 5.0.0-alpha-8, 4.0.21
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Major
> Fix For: 5.0.0-alpha-9
>
>
> Consider the following:
> {code:groovy}
> class C extends HashMap<String,String> {
> private Object f = 'field'
> private static Object g = 'field'
> @groovy.transform.TypeChecked
> void test() {
> {->
> println f // entry
> println g // field
> println this.f // entry or field (if SC)
> println this.g // field
> }()
> }
> }
> new C().test()
> {code}
> Fixes in Groovy 3 [1][3] and 4 [2][3] have made it so that "g" and "this.g"
> resolve to the static field (even from outer class). Groovy 5 has dropped
> this special case and should go through the closure's {{getProperty}}
> protocol (see GROOVY-10985). This is at least consistent with "g" and
> "this.g" appearing outside of a closure.
> However, "f" and "this.f" have some inconsistencies. "f" resolves to entry
> for STC and SC. "this.f" resolves to field at compile time for STC and SC.
> But to entry for STC and field for SC at run time. In Groovy 5, both
> "this.f" and "this.g" exhibit this difference.
> Should "this.f" be entry within closure as "f" is for all cases? Or should
> only the STC inferred type be fixed to match the run time behavior, leaving
> SC unchanged?
