+
+<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>
