Eric Milles updated GROOVY-10436:
---------------------------------
Fix Version/s: (was: 5.0.0-alpha-1)
> STC: closure parameter type-checking: declared vs inferred
> ----------------------------------------------------------
>
> Key: GROOVY-10436
> URL: https://issues.apache.org/jira/browse/GROOVY-10436
> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Affects Versions: 4.0.0-rc-2, 3.0.12
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Major
> Fix For: 3.0.12, 4.0.4
>
>
> Consider the following:
> {code:groovy}
> import java.util.function.Consumer
> def <T> T m(Consumer<? super T> c) {
> // ...
> }
> @groovy.transform.TypeChecked
> void test() {
> this.m { Number n ->
> def big = n.toBigInteger()
> }
> }
> {code}
> Recent fixes for closure param STC (GROOVY-8917, GROOVY-10049, GROOVY-10053,
> etc.) are producing an error for the param "expected Object actual Number"
> and an error for the call expression "cannot find method
> Object#toBigInteger()".
> {{StaticTypeCheckingVisitor#inferClosureParamterTypes}} does not use closure
> expressions to determine placeholder types and there are no other type
> witnesses.
