[Soot-list] A BUG about JimpleConstructorFolder and Line number or any options I did not turn on?

[Eric Bodden]

Hmm, I looked at the code and actually the only statements we delete
and newly generate are copy statements, which usually don't have a
line number associated anyway. So I doubt that this is your actual
problem.
