[Soot-list] Problem in Call graph construction

[Eric Bodden]

Hi Asif.

There is several problems with your code, which arise that you are
using Soot in a rather "manual" way instead of just letting it run its
pre-defined configuration passes.


The easiest way to run CHA is to simply enable it through the
respective phase options:
http://www.sable.mcgill.ca/soot/tutorial/phase/index.html

Your main method should just access the PackManager through
PackManager.v() and add a SceneTransformer to the "wjtp" pack. This
SceneTransformer will then be run just after the CHA has finished, so
that you can access information from the CHA.

In the end, your main method should call Soot's main method with the
original argument array.

To then run the analysis, just call your main method with -w as an
argument (to enable all the w* packs) and with InheritanceTest as an
argument, to analyze your class.
