Why Class.forName("BumpTest"), not BumpTest.class?

Andy Turner :

In JLS Sec 8.4.3.6, synchronized methods, it says:

class BumpTest {
    // ...
    static synchronized void classBump() {
        classCount++;
    }
}

has exactly the same effect as:

class BumpTest {
    // ...
    static void classBump() {
        try {
            synchronized (Class.forName("BumpTest")) {
                classCount++;
            }
        } catch (ClassNotFoundException e) {}
    }
}

This looks odd to me, not to mention over-complicated: why use Class.forName("BumpTest"), not BumpTest.class? It's not possible that BumpTest isn't loaded, because it's executing code from that class, after all. And writing it as it is, the checked ClassNotFoundException has to be caught and swallowed.

Is there a particular reason to write it in this way?

It appears to just be a really, really old example, older than class literals. The same example appears in the JLS 1.0, before class literals were introduced.
