Interprocedural exception analysis for Java
Byeong‐Mo Chang, Jang-Wu Jo, Kwangkeun Yi, Kwang-Moo Choe · 2001
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 designed and implemented based on set-constraint framework. Its cost-effectiveness is suggested by sparsely analyzing the program at method-level (hence reducing the number of unknowns in the flow equations). We have shown that our exception analysis can effectively detect uncaught exceptions for realistic Java programs. 1. INTRODUCTION Exception facilities in Java allow the programmer to define, throw and catch exceptional conditions. Exceptional conditions are brought (by a throw ...
