> When the DBCPConnectionService Registers a Driver it gets added to the DriverManager which exists in the System Classloader.  This will prevent the InstanceClassLoader that the DBCPConnectionService is running in from being Garbage Collected.  
> The Driver should be deregistered onRemove to prevent this leak.
