|
|
* 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).
