| * 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). |
