Exception Analysis for Java

Abstract

. Current JDK Java compiler relies too much on programmer's specification for checking against uncaught exceptions of the input program. It is not elaborate enough to remove programmer's unnecessary handlers (when programmer's specifications are too many) nor suggest to programmers for specialized handlings (when programmer's specifications are too general). We propose a static analysis of Java programs that estimates their exception flows independently of the programmer's specifications. This analysis is an extension of a class analysis to Java's exception mechanism. Its cost-effectiveness balance is suggested by sparsely analyzing the program at method-level (hence reducing the number of unknowns in the flow equations). 1 Introduction The current Java compiler relies on the programmer's specifications to check that the input program will have no uncaught exceptions at run-time. The programmers have to declare in a method definition any exception class whose exceptions ma..
