/**
* Specifies that the dynamic proxy should find another method (R3) that
* performs the same function, and redirect the method invocation to that
* R3 method.
*
* An R3 method is a method of the same name as this method, but which takes
* an additional AuthContext parameter as the next-to-last argument.
* The proxy constructs a new argument list by adding a null AuthContext
* argument to the provided argument list and calls invokes the R3 method
* such that authentication checks are performed as if the R3 method had been
* invoked directly. The actual body of this method should never get called, so
* it is probably appropriate to throw a runtime exception as the method body,
* as it exists solely to satify the RMI interface defintiion.
*
* Note that it is an error if the R3 method for an R2 compatibility method is
* not implemented within the same class. If either class is re-implemented
* on a derived class then both must be re-implemented.
