> I have the following Groovy program.
> {code:groovy}
> @groovy.transform.CompileStatic
> class Main<I extends B<Character>> {
>   void main() {
>     C<I> x = (C<I>) null
>     x.foo().bar(null)
>   }
> }
> class A<I, E extends I>  {
>   void bar(E y) {}
> }
> class B<T> {}
> class C<S extends B<Character>> {
>   A<S, ? extends S> foo() { (A<S, ? extends S>) null}
> }
> {code}
> h2. Actual Behavior
> {code:java}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
> Main.groovy: 4: [Static type checking] - Cannot call A#bar(B) with arguments [<unknown parameter type>]
>  @ line 4, column 5.
>        x.foo().bar(null)
>        ^
> 1 error
> {code}
> h2. Expected behavior
> Compile successfully.
> h2. Comment
> This should be a regression bug because groovyc 4.0.0-alpha-3 compiles the program successfully
> h2. Affected Version
> master (commit: e453db968df3753dc6c26d51168b944137c8e4b1)
