> When the HikariCPConnectionPool loads a Driver it registeres to the
> DriverManager on class load with many current drivers. The DriverManager
> exists in the System Classloader. This will prevent the
> InstanceClassLoader that the HikariCPConnectionPool is running in from being
> Garbage Collected.
> The Driver should be deregistered onRemove to prevent this leak.
