A Formal Approach to Fixing Bugs [chapter]

Sara Kalvala, Richard Warburton
2011 Lecture Notes in Computer Science  
The specification language uses a combination of syntactic rewrite rules and dataflow analysis generated from temporal logic based conditions.  ...  We propose a combination of source code and bytecode analyses: this allows for using the control flow in the bytecode to help identify the bugs while generating corrected source code.  ...  But if an automated tool is not designed to consider the specification of the program, there is the risk of introducing new bugs into a currently working system.  ...
