Re: old to new soot questions

The stack trace looks more like a problem with the classes that you are
analyzing, rather than anything caused by calling into Soot incorrectly.
It's saying that the Buffer class doesn't have the constructor that is
being referenced. Perhaps, due to problems with the classpath, Soot is
analyzing a different Buffer class file than you expect. Also strange
is the signature in that stack trace: it says it is looking for a
constructor taking an array, but it doesn't say what type of array.
What kinds of class files are you analyzing?
