Static type checking

[cazacugmihai]

Hi, 

I have a problem running this code:
 
import groovy.transform.CompileStatic
import java.util.function.Function
 
@CompileStatic
class Test {
        static void main(String[] args) {
               // this code fails 
                Function<Integer, Integer> fct = { Integer n ->
                        -n
                }
 
                // this one works but it is too verbose
                // Function<Integer, Integer> fct = ({ Integer n ->
                //      -n
                // } as Function<Integer, Integer>)
 
                println fct.apply(10)
        }
}

The error:

Test.groovy: 9: [Static type checking] - Incompatible generic argument
types. Cannot assign java.util.function.Function <java.lang.Integer,
groovy.lang.Closure> to: java.util.function.Function <Integer, Integer>
 @ line 9, column 36.
                Function<Integer, Integer> fct = { Integer n ->
                                      ^
1 error

Is there a bug in groovy related to @CompileStatic or maybe I am missing
something else? I just don't want to write redundant code.

Thanks,
Mihai
