Glorified classes in the Java language
<p>Some classes in the standard Java API are treated slightly different from other classes. I'm talking about those classes that couldn't be implemented without special support from the compiler and/or JVM.</p>

<p>The ones I come up with right away are:</p>

<ul>
<li><code>Object</code> (obviously) as it, among other things doesn't have a super class.</li>
<li><code>String</code> as the language has special support for the + operator.</li>
<li><code>Thread</code> since it has this magical start() method despite the fact that there is no bytecode instruction that "forks" the execution.</li>
</ul>

<p>I suppose all classes like these are in one way or another mentioned in the JLS. Correct me if I'm wrong.</p>

<p>Anyway, what other such classes exist? Is there any complete list of "glorified classes" in the Java language?</p>
