[Soot-list] problem when trying to retrieve active body for methods woven using AOP

[Eric Bodden]

Hi Peng.

Wha do you mean by "cannot get the active body"? Does the method have
no body (according to Soot) or can Soot simply not find any line
number information for the method. The latter would not surprise me
because the method likely holds generated code.
