>                 Key: GROOVY-7729
>                 URL: https://issues.apache.org/jira/browse/GROOVY-7729
>             Project: Groovy
>          Issue Type: Bug
>          Components: groovy-jdk
>    Affects Versions: 2.4.4, 2.4.5
>         Environment: JDK 1.8.0_51/win32
>            Reporter: Fabiano Biagini
>            Priority: Minor
>
> {noformat}
> @groovy.transform.CompileStatic
> void bug() {
>     int a = [1,2,3].sum()
> }
> {noformat}
> The code above works correctly with CompileDynamic, but CompileStatic will produce the following error:
> {noformat}
> [Static type checking] - Cannot assign value of type java.lang.Object to variable of type int
> {noformat}
> Seems to be a problem of DefaultGroovyMethods.sum(Iterable).
> I think it just need to be changed from
> {noformat}
> public static Object sum(Iterable self)
> {noformat}
> to
> {noformat}
> public static <T> T sum(Iterable<T> self)
> {noformat}
