 <p>Note that no type parameters are necessary.

-<h2><a name="debug">9. Debug</h2>
+<h2><a name="boxing">9. Boxing/Unboxing</h2>
+
+<p>Boxing and unboxing in Java are syntactic sugar.  There is no bytecode for
+boxing or unboxing.  So the compiler of Javassist does not support them.
+For example, the following statement is valid in Java:
+
+<ul><pre>
+Integer i = 3;
+</pre></ul>
+
+<p>since boxing is implicitly performed.  For Javassist, however, you must explicitly
+convert a value type from <code>int</code> to <code>Integer</code>:
+
+<ul><pre>
+Integer i = new Integer(3);
+</pre></ul>

 <p>Set <code>CtClass.debugDump</code> to a directory name.
 Then all class files modified and generated by Javassist are saved in that
