I highly doubt that Soot is just making up a method for the fun of it.
Therefore, the obvious answer is that the method "class$" actually exists.
Are you sure you are using a classfile generated from the source code you
displayed, or are you operating on a classfile that was distributed to you
(i.e. you did not compile it yourself)?

If you want to know for sure use the "javap" disassembler tool to print
out a list of methods in the class. javap comes with the JDK. It will give
you method bytecode as well, if you want, with the -c option.

I'm pretty sure you are going to find that the class you are instrumenting
actually does have a "class$" method.

Hope this helps,

Michael
