Description

To replicate the issue:

1. Add a DBCPService controller service.
2. Configure service. For the Driver Url use "file://tmp/non-existent-file" or use an invalid Driver Class Name.
3. Click Apply.
4. Click Enable.

The UI will show the spinner indefinitely, as the service will keep failing to enable because it throws Exceptions from its @OnEnabled method. The UI should provide some sort of indication that this is occurring. Otherwise, it appears to the user that the system is non-responsive.
