/**
 * There are three potential exception conditions which can occur
 * reading annotations:
 *
 * EnumConstantNotPresentException - "Thrown when an application tries
 * to access an enum constant by name and the enum type contains no
 * constant with the specified name."
 *
 * AnnotationTypeMismatchException - "Thrown to indicate that a
 * program has attempted to access an element of an annotation whose
 * type has changed after the annotation was compiled (or serialized)"
 *
 * TypeNotPresentException - "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."
 *
 * The test reads an annotation, DangerousAnnotation, which can
 * display all three pathologies. The pathologies are <em>not</em>
 * present when the version1 sources are used but are present with the
 * version2 sources. The version2 sources remove an enum constant
 * (EnumConstantNotPresentException), change the return type of an
 * annotation method (AnnotationTypeMismatchException), and remove a
 * type whose Class literal is referenced (TypeNotPresentException).
