[Soot-list] Adding a class to scene/hierarchy

[Eric Bodden]

Hi Derek.

addBasicClass is not going to help you there. This method merely adds
the class to a list of classes to be loaded when Soot starts up. When
you call the method, you are probably calling it at a point in time
where it is already too late.

You could try the following:
