Another example:
public class Example {
public void methodA(String str) {
java.util.Optional.ofNullable(str)
.flatMap(this::getMyObject); //missing reporting of error on
such line
}
public java.util.Optional<Runnable> getMyObject() {
return null;
}
}
And only shown error on tab (indicator) and in Action items "Error incompatible
types: invalid method reference method getMyObject in class", but nothing
inside editor itself.

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) {}}{\{ }
}
}}}
And only shown error on tab (indicator) and in Action items "Error incompatible

> Affects Versions: 12.0, 11.2, 11.3
> Environment: OpenJDK 11.0.2
> Gradle 6.4.1
> Reporter: Netbeans User 2019
> Priority: Major

> 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.
