>             Project: Groovy
>          Issue Type: Bug
>          Components: Static compilation, Static Type Checker
>    Affects Versions: 3.0.6
>            Reporter: Konstantin Nisht
>            Assignee: Eric Milles
>            Priority: Major

> @CompileStatic
> class A {
>     static <U> void foo(U a, U b) {}
>     static void main(String[] args) {
>         foo(1, "")
>     }
> }
> {code}
> The following code fails to compile with error
> {{Groovyc: [Static type checking] - Cannot call <U> A#foo(U, U) with arguments [int, java.lang.String]}}
>  {{U}} should be inferred to LUB(Integer, String), hence the call should be successful.
