  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).
