[Soot-list] ThreadLocal class

[Eric Bodden]

Hello.

Since ThreadLocal is just a java class like any other class, Soot
certainly supports it. I am assuming that you are doing something
wrong in the code generation.

My estimation would be that for every field you need to...

1.) create a new sub-class of ThreadLocal
2.) construct an initialValue method in that subclass
3.) replace the field and assign to it at the right point in time
4.) replace all references to the field
