there's a better way than declaring from time to time the following map:
private static final Map<String, Class> primitiveToClass = new HashMap<String, Class>() {{
put("boolean", Boolean.class);
put("double", Double.class);
put("float", Float.class);
put("long", Long.class);
put("int", Integer.class);
}};
(Used Crazybob's contraption, but that's not the point.)
