It does't belong to shutdown, it is the first message from the next startup, like

2018-07-02 18:16:43 0 [ERROR] mysqld: Can't open shared library 'handlersocket.so' (errno: 1, Loading of beta plugin handlersocket is prohibited by --plugin-maturity=gamma)

The reason of the failure is given in the error message. Handlersocket's maturity is beta, so it doesn't load with plugin-maturity=gamma.
