Examples from A Survivor's Guide to Java Program Analysis in Soot (Survivor's Guide) extracted from the Soot source tree in September 2015, with additional examples from the thesis Soot: A Java Bytecode Optimization Framework by Raja Vallee-Rai that are not already included in the Survivor's Guilde.
The original Survivor's Guide website is http://www.brics.dk/SootGuide/ and Vallee-Rai's thesis can be found at http://www.sable.mcgill.ca/publications/thesis/#korMastersThesis
To satisfy the dependecies, you will of course need soot-trunk.jar from https://github.com/Sable/soot and paddle-0.3.jar from http://www.sable.mcgill.ca/paddle/
