Java Streams: find if stream contains null

Most probably a duplicate, however I was not able to find any particular one.

Given

public static void main(String[] args) {
    System.out.println(
            Arrays.asList(null, null, 1)
                    .stream()
                    .filter(obj -> obj == null)
                    .findAny()
                    .isPresent()
    );
}

Expectation

Should at least work (i.e return false because findAny returns Optional).

Actual

NullPointerException is thrown

Question

Is it a bug or a feature?

Thanks for your opinion and explanation.
