If the Predicate is defined inside Never, this program never completes.

Main.java

import java.util.List;
import java.util.function.Predicate;

public class Main {
    static final Predicate<String> test = s -> s.length() > 6;

    static class Never {
        // static final Predicate<String> test = s -> s.length() > 6;
        static final List<String> fruit = List.of(
                "Apples", "Bananas", "Pears",
                "Oranges", "Tomatoes", "Cucumber");
        static final long longFruit = fruit.parallelStream()
                .filter(test)
                .count();
    }

    public static void main(String... args) {
        System.out.println("longFruit: " + Never.longFruit);
    }
}

Could you please explain why this happen?
