[java] UnnecessaryBoxing false positive in PMD 7.0.0 in lambda

[julius-d]

Hi!
I am currently trying to update from 6.55.0 to PMD 7.0.0.

Affects PMD Version: 7.0.0

Rule: UnnecessaryBoxing

Code Sample demonstrating the issue:

import java.util.Optional;

public class Example {

  record Item(int cents) {}

  Long map(Item item) {
    return Optional.ofNullable(item).map(it -> Long.valueOf(it.cents())).orElse(null);
  }
}

Outcome:

PMD Failure: Example:10 Rule:UnnecessaryBoxing Priority:3 
Unnecessary explicit conversion from int to Function<? super Item, ? extends Long>

Running PMD through: maven-pmd-plugin 3.21.2
