Class ConcurrentAccessException

  • All Implemented Interfaces:
    public class ConcurrentAccessException
extends AccountException
    Thrown when an authentication attempt has been received for an account that has already been authenticated (i.e. logged-in), and the system is configured to prevent such concurrent access.

    This is useful when an application must ensure that only one person is logged-in to a single account at any given time.

    Sometimes account names and passwords are lazily given away to many people for easy access to a system. Such behavior is undesirable in systems where users are accountable for their actions, such as in government applications, or when licensing agreements must be maintained, such as those which only allow 1 user per paid license.

    By disallowing concurrent access, such systems can ensure that each authenticated session corresponds to one and only one user at any given time.
