All Implemented Interfaces:

java.io.Serializable

public class AlreadyExistsException

extends JmiException

Exception thrown by refCreateInstance and create methods when a client attempts to create the second instance of a singleton.
I think we should rather return the existing instance of singleton from the create method without throwing this exception. This behaviour is more common for singletons.
