Exception handling is notoriously difficult for programmers whereas transactional memory has been instrumental in simplifying concurrent programming. In this chapter, we describe how the transactional syntactic sugar simplifies the exception handling problems both when writing sequential and concurrent applications. We survey exception handling solutions to prevent applications from reaching an inconsistent state in a sequential environment on the one hand, and extend these solutions to also prevent concurrent execution of multiple threads from reaching an inconsistent state, on the other hand. The resulting technique greatly simplifies exception handling and is shown surprisingly efficient.
