I have Spring boot application, that goes to database using HikariCP.
The thing is, when application gets stop (SIGTERM or other) signal, it must go to database and change some data, after that it closes (“gracefull shutdown”). This logic is written in myShutdownHook (Runtime.getRuntime().addShutdownHook(myShutdownHook)). So the app needs to use connection pool for that. But problem is, that Hikari pool closes right after getting stop signal:

2022-09-18 18:26:44,796 INFO  [SpringApplicationShutdownHook] com.zaxxer.hikari.HikariDataSource: HikariPool-1 - Shutdown initiated...
2022-09-18 18:26:44,798 INFO  [SpringApplicationShutdownHook] com.zaxxer.hikari.HikariDataSource: HikariPool-1 - Shutdown completed.

And context is closing before my logic is completed. How can I make HikariCP not to close before my logic in myShutdownHook is done?
