28/**
29 * Thrown when an application tries to access a type using a string
30 * representing the type's name, but no definition for the type with
31 * the specified name can be found.   This exception differs from
32 * {@link ClassNotFoundException} in that <tt>ClassNotFoundException</tt> is a
33 * checked exception, whereas this exception is unchecked.
34 *
35 * <p>Note that this exception may be used when undefined type variables
36 * are accessed as well as when types (e.g., classes, interfaces or
37 * annotation types) are loaded.
38 * In particular, this exception can be thrown by the {@linkplain
39 * java.lang.reflect.AnnotatedElement API used to read annotations
40 * reflectively}.
