I'm getting stack traces like this:

What are GeneratedMethodAccessor1, GeneratedMethodAccessor2, GeneratedMethodAccessorN and what might be causing them to not be found? I am doing some byte code rewriting at run time, but only before the class is loaded, and the first several calls through reflection work fine. I'm wondering if this is happening after the JIT compiler gets a hold of my code, but I don't even have a very good idea of how to start debugging this.
