[Soot-list] Soot exception: There is no main class set!

Hi again.

I now see what may be the problem... So you are using the very class
that Soot is supposed to analyze to also bootstrap Soot? That is
calling for trouble. The code that makes up your program analysis
should always be totally separated from the code you are analyzing.
Otherwise it'S quite hard to get the classpath right....
