 careful when you place an Iterator into the context.

+<p>Not all classes are instantiable.  Classes like <code>java.lang.Math</code>
+do not provide any public constructor, and yet may contain useful static methods.
+In order to access these static methods from a template, you can simply add the
+class itself to the context:
+</p>
+
+<source><![CDATA[
+context.put("Math", Math.class);
+]]></source>
+
+<p>This will allow you to call any public static method in <code>java.lang.Math</code>
+on the <code>$Math</code> reference in the template.
