/**
* Dummy class used during JNI initialization. The JNI functions want
* to be able to create objects, and the VM needs to discard the references
* when the function returns. That gets a little weird when we're
* calling JNI functions from the C main(), and there's no Java stack frame
* to hitch the references onto.
*
* Rather than having some special-case code, we create this simple little
* class and pretend that it called the C main().
*
* This also comes in handy when a native thread attaches itself with the
* JNI AttachCurrentThread call. If they attach the thread and start
* creating objects, we need a fake frame to store stuff in.
