HikariCP and exiting a program

[JohnMerlino1]

I am wondering if I need to call System.exit(1) in my program, do I need to perform any kind of cleanup with HikariCP, kind of like flushing a buffer with files or running shutdown with executorservice? Currently, when I call getConnection() on HikariDataSource, I have a finally block that closes the statement, result and connection (actually I assume the connection is returned to the pool):

        if (stmt != null)  
            {  
                stmt.close();
            }  

            if (result != null)  
            {  
                result.close();  
            }  

            if (conn != null)  
            {  
                conn.close();  
            } 

I would like to know if I need to do anything else when I exit my program.

You should call close() or shutdown() on the HikariDataSource before you exit. This will ensure that all connections to the database in the pool are closed.
