Exiting sessions after state invalidation avoids errors that can occur when applications mishandle an invalid state.

When a stateful PL/SQL package undergoes modification, the sessions that have an active instantiation of the package receive an ORA-4068 error when they attempt to run the package. When SESSION_EXIT_ON_PACKAGE_STATE_ERROR is set to TRUE, the session immediately exits instead of raising ORA-04068. This can be advantageous because many applications are better equipped to handle a session being discarded, and failing to catch errors related to session state, such as ORA-04068, can lead to silent data corruption.
