Object.with seems to lose typing when generics are used

@groovy.transform.CompileStatic
class Test {
  static List<String> a( String s ) {
    s.with { String it -> [ "$it" ] }
  }
}

assert Test.a( 'tim' ) == [ 'tim' ]

[Static type checking] - Cannot return value of type java.lang.Object on method returning type java.util.List <String>
