[Soot-list] Transforming java library classes

[Khilan Gudka]

Dear Chris,

Unfortunately that didn't work. This is really weird, as soot is
clearly adding the methods. Debug output I am generating:

Adding cos96 to java.lang.Math
Successfully added? true.

The true value is obtained by doing a contains check on the list
returned by SootClass.getMethods().
