[Soot-list] Pack Manager and removing phase

[Pallavi Majumder]

  Hi Steven,

The stack trace is correct. What I am basically doing is instrumenting  
my code, if I run the Pack Managers together the output instrumented  
code is blank(null).

The reason why I am running it twice is that I am adding a different  
transform the second time.

Best,
Pallavi
