[Soot-list] Exception during "Using Soot as a Program Optimizer" tutorial

[Eric Bodden]

This has to be a classpath issue. I assume your JVM gets confused
because you have JAR files with a potentially overlapping but
inconsistent set of classes on your classpath.

Could you try with this command line?

java -cp /homes/rrueth/Soot/sootclasses- 2.2.3.jar:. soot.Main -O Hello
