/**

 * Thrown when an application tries to access a type using a string

 * representing the type's name, but no definition for the type with

 * the specified name can be found.   This exception differs from

 * {@link ClassNotFoundException} in that {@code ClassNotFoundException} is a

 *

 * <p>Note that this exception may be used when undefined type variables

 * are accessed as well as when types (e.g., classes, interfaces or

 * annotation types) are loaded.

 * In particular, this exception can be thrown by the {@linkplain

 * java.lang.reflect.AnnotatedElement API used to read annotations

 * reflectively}.
