Abstract: Exception handling suffers from a fluke in its evolution. Some time in the 1970's, a researcher called Goodenough introduced the exception handling mechanism, known today as the tcode{try...catch} construct. At about the same time, two fellows called Parnas and Würges published a paper about "undesired events". This paper appears forgotten. The funny thing is, Parnas and Würges effectively described how to emph{use} exception handling mechanisms. There is a need to respond to this undesired event. Exception handling suffers from lack of design guidelines and a number of inconsistencies with the object-oriented paradigm, among other things. The thesis' main contribution is creating a library of exception challenges and the evaluation of safety facades, an approach that introduce an architecture and guidelines for designing exception handling. Through qualitative evaluation, this thesis shows how safety facades form an interesting new approach to exception handling.
