+/**
+ * <p>
+ * Compile-time representation of Java type system.
+ *
+ * <p>
+ * These classes are used as TypeT and ClassDeclT of the model parameterization. This implementaion is designed to be
+ * capable of representing pre-existing classes (such as java.lang.String) as well as the generated classes (represented
+ * as JDefinedClass.)
+ *
+ * <h2>Handling of Primitive Types</h2>
+ * <p>
+ * Primitive types have two forms (int and Integer), and this complicates the binding process. For this reason, inside
+ * the front end, we always use the boxed types. We'll use the unboxed form only in the back end when we know the field
+ * doesn't need to represent the null value.
