[Soot-list] Pack Manager and removing phase

[Arzt, Steven]

Hi Pallavi,

To understand what happens here, I would need a lot more detail. What do you mean by “null result”? Is there some exception? What is the stack trace?

Secondly, why do you attempt to run the PackManager twice at all? This is not the intended use of the PackManager and I don’t really see a reason why this should be necessary.

Best regards,
  Steven

Hello All,

I execute, the following code twice. Each time for different classname. However, when I execute them in the same program run the result of the second transform is incorrect.

PackManager.v().getPack("jtp")
.add(new Transform("jtp.mainInstrumentation", classname));

When I execute the PackManager twice in 2 different program runs, everything works fine but executing them together creates a null result. I tried to remove the particular phase name before the second execution, but that does not help.

Just to make it clear, here is what I tried:
PackManager.v().getPack("jtp")
.add(new Transform("jtp.mainInstrumentation", new XMLConversion()));
PackManager.v().getPack("jtp").remove("jtp.mainInstrumentation");
PackManager.v().getPack("jtp")
.add(new Transform("jtp.xmlInstrumentation", new XMLConversion()));

jtp.mainInstrumentation works fine, but jtp.xmlInstrumentation does not work here. However , if I execute them individually, I get perfect results.

Please note that I want them to use "jtp" and not "wjtp" or any other packs.

I would really appreciate if anyone has an idea why this happens in PackManager.

Thanks,
Pallavi
