Business process models describe the way of working in an organization. Typically, business process models distinguish between the normal flow of work and exceptions to that normal flow. However, they often present an idealized view. This means that unexpected exceptions – exceptions that are not modelled in the business process model – can also occur in practice. This has an effect on the effi...

Interface exceptions (explicitly declared exceptions that a method can propagate outside) are an inherent part of the interface describing the behaviour of a particular class of objects. Evolution of system behaviour is thus necessarily accompanied by and reflected in the evolution of interface exceptions. While evolution of normal system behaviour is adequately supported by various language me...

Exceptions to legal rules often represent a step outside the bounds of existing law, specifically, outside the bounds of the rules and principles to which they are exceptions, and their creation is therefore often an exercise of true judicial power—the ability to act unfettered by preexisting legal constraint. Professor Frederick Schauer, in his paper Exceptions, largely ignores this intuition....

In this paper, we first present a static analysis based on set-based framework, which estimates exception propagation paths of Java programs. We construct an exception propagation graph from the static analysis information, which includes the origin of exceptions, handler of exceptions, and propagation paths of exceptions. We have implemented the exception propagation analysis and a visualizati...

The use of exceptions in programming languages is usually reserved for exceptional conditions. This is a narrow view of exceptions, however. We demonstrate how exceptions can be used to express common programming language constructs, and thus form the basis of a new type of exception-based programming language. We also generalize exceptions so that they may be thrown into a program’s future exe...

Rules, and exceptions to such rules, are ubiquitous in many domains, including language. Here we used simple artificial grammars to investigate the influence of 2 factors on the acquisition of rules and their exceptions, namely type frequency (the relative numbers of different exceptions to different regular items) and token frequency (the number of exception tokens relative to the number of re...
