+/**
+ * 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).
