Abstract
A system, method and article of manufacture are provided for minimizing the amount of changes that need to be made to exception handling logic when new exceptions are added. Exceptions are organized into hierarchies in a polymorphic exception handler. A root of one of the hierarchies in which an exception occurs is caught. The exception is instructed to rethrow itself. The rethrown exception is caught and identified. A type of the rethrown exception is determined and a message is outputted indicating the type of the rethrown exception.
