call of a method from x users

I have a class A with a public method B on a server

Users access this particular method via RMI.

The question:

If the Users called the method B (at the same time) from the same instance of A, did they use the same method or a separate one.

One "instance" of the method for each user's call or only one on the server's stack for everyone.
