40 * There are three potential exception conditions which can occur
41 * reading annotations:
42 *
43 * EnumConstantNotPresentException - "Thrown when an application tries
44 * to access an enum constant by name and the enum type contains no
45 * constant with the specified name."
46 *
47 * AnnotationTypeMismatchException - "Thrown to indicate that a
48 * program has attempted to access an element of an annotation whose
49 * type has changed after the annotation was compiled (or serialized)"
50 *
51 * TypeNotPresentException - "Thrown when an application tries to
52 * access a type using a string representing the type's name, but no
53 * definition for the type with the specified name can be found."
54 *
55 * The test reads an annotation, DangerousAnnotation, which can
56 * display all three pathologies. The pathologies are <em>not</em>
57 * present when the version1 sources are used but are present with the
58 * version2 sources. The version2 sources remove an enum constant
59 * (EnumConstantNotPresentException), change the return type of an
60 * annotation method (AnnotationTypeMismatchException), and remove a
61 * type whose Class literal is referenced (TypeNotPresentException).
