------------------------------
> STC: extension method cannot provide map property (read mode)
> -------------------------------------------------------------
>
> Key: GROOVY-11370
> URL: https://issues.apache.org/jira/browse/GROOVY-11370
> 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, 4.0.22
>
>
> Consider the following:
> {code:groovy}
> @TypeChecked
> void test() {
> def map = [:]
> print map.metaClass
> }
> test()
> {code}
> The script prints "null" (before Groovy 5) indicating that "getMetaClass()"
> extension method is not used. However, node metadata indicates that the
> extension method is used. For example, adding "Number n = map.metaClass"
> says: "Cannot assign value of type groovy.lang.MetaClass to variable of type
> java.lang.Number"
> GROOVY-5001, GROOVY-5491, GROOVY-5568, GROOVY-9115, GROOVY-9123
