    `static String` | `ARGS_MAINTAIN_STATE_AFTER_EXCEPTION` Argument name that is intended to be used with a session which when its value is `true` makes it so that a processing error or request timeout will not close the session, but leave it to continue processing in whatever state it may hold.

      Implementations that set this key should consider using one of these two recommended value types:

      - A `List` implementation containing references for which `String#valueOf(Object)` produces a meaningful return value. For example, a list of strings.
      - Otherwise, any single non-list object for which `String#valueOf(Object)` produces a meaningful return value. For example, a string.
