----------------------------------------------

Another example:

{{public class Example {}}{{    public void methodA(String str) {
            java.util.Optional.ofNullable(str)
                .filter((s)->s.startsWith("example"))
                .flatMap(this::getMyObject)
                .ifPresent((o)->{
                    o.someMethod(str);
                });
        }}}{{        public java.util.Optional<MyObject> getMyObject() {}}{{            return java.util.Optional.empty();
        }}}{{        public static class MyObject {}}{{            public void someMethod(String str) {}}{{            }
        }
}}}

>             Project: NetBeans
>          Issue Type: Bug
>          Components: java - Compiler, java - Editor, platform - Action Items
>    Affects Versions: 11.2, 11.3
>         Environment: Apache Netbeans 11.2 and even 11.3
> OpenJDK 11.0.2
>            Reporter: Netbeans User 2019
>            Priority: Major
>              Labels: compiler

> public static void main(String[] args) {
>  
>  List<Integer> z = List.of(1,2,3);
>  z.stream()
>  .map(SandboxTemp1::ou)
>  .toString();
> }
> private static int ou(String o) {
>  return 0;
> }
> There is missing to be shown as error on such line.
> It is seen as issue in action items and red indicator in tab next name of file, but no issue shown in editor itself.
> In actions items you can see:
> Error incompatible types: invalid method reference incompatible types: java.lang.Integer cannot be converted to java.lang.String ... :23
> This is not one case, but this happens for different types so not only that one from example.
