[Soot-list] Does soot preserve java bytecode offset information?

[Jan Peter Stotz]

Hi Shuyang,

source line numbers are usually converted to tags, in detail to
instances of soot.tagkit.SourceLineNumberTag. You will find those tags 
if you use the command-line option -keep-line-number.

You can retrieve the line number tags when calling on a unit getTags() 
and filter them for SourceLineNumberTag instances.
