/**
* 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).
