Overriding equals and hashCode with Guava and Objects class

We usually use IDE to override equals and hashCode methods in our classes.
Let's see how IntelliJ IDEA 11 copes with a simple class with 3 fields:
Even though the class seems simple, the methods' size is a little bit scary.
Using EqualsBuilder and HashCodeBuilder from Apache Commons Lang makes the methods much smaller, however introduces one major flaw: it uses reflection, which isn't a speed demon.
To the rescue comes Guava, which makes these methods simpler and more readable:

	public class Book {
	private String author;
	private String title;
	private int pages;
	public Book(String author, String title, int pages) {
	this.author = author;
	this.title = title;
	this.pages = pages;
	}
	@Override
	public boolean equals(Object obj) {
	if (obj == null) {
	return false;
	}
	if (getClass() != obj.getClass()) {
	return false;
	}
	final Book other = (Book) obj;
	return Objects.equal(this.author, other.author) && Objects.equal(this.title, other.title) && Objects.equal(this.pages, other.pages);
	}
	@Override
	public int hashCode() {
	return Objects.hashCode(author, title, pages);
	}
	}

If you're working on a project in which you can use Java 7, it provides a similar solution without having to use any external library:

	public class Book {
	private String author;
	private String title;
	private int pages;
	public Book(String author, String title, int pages) {
	this.author = author;
	this.title = title;
	this.pages = pages;
	}
	@Override
	public boolean equals(Object obj) {
	if (obj == null) {
	return false;
	}
	if (getClass() != obj.getClass()) {
	return false;
	}
	final Book other = (Book) obj;
	return Objects.equals(this.author, other.author) && Objects.equals(this.title, other.title) && Objects.equals(this.pages, other.pages);
	}
	@Override
	public int hashCode() {
	return Objects.hash(author, title, pages);
	}
	}

At the time of writing this, IDEA 11 doesn't support generating equals and hashCode using Guava or Objects class from Java 7. I created a plugin that provides such possibility:
