  General Support #8: Unable to launch a custom blueprint instance:
  unexpected error or no feedback at all

As both a simple test and a case study for my FiWare project, I'm trying 
to create a MySql service. All what I need is a VM running MySql and a 
connection string to it.

Maybe I'm missing some point, but I found no blueprint for such a simple 
scenario. I can find only MySql + NodeJS, which is not what I need as 
I'm not going to use JavaScript for my complex data handling logic, nor 
Node in my scenario looks like an ideal candidate. I thus tried to 
create a new one, by creating a new blueprint, checking the public IP 
option (I suppose I'm going to need an endpoint to access from my 
software via TCP) and adding just a single MySql tier: I don't know it 
this would provide the desired result (i.e. a VM ready to use with a 
given connection string), but I was going to learn by trial.

(BTW, in the Lab the distinction between PaaS and IaaS modules seems 
unclear. I'm still wondering if and how I can just fire a ready-to-use 
MySql instance with a few clicks, or if I'll have to manually configure 
a VM once instantiated so I can finally get a connection string.)

Once this was completed, I tried to launch an instance of this new 
blueprint: I entered a name and description in the Launch Blueprint 
Instance dialog, and clicked the Launch button. After 15 minutes of wait 
time, with the client side UI stuck with the spinning wheel at its 
center, I closed and reopened the Lab. Of course no instance was there. 
No error was reported.

I tried this several times and once I got this error, but I could not 
further reproduce it:

Unexpected error creating environment com.telefonico.euro_iaas.paasmanager.model.EnvironmentInstance at aaaf.Description:null

I'm using the Spain region as recommended; anyway, it is the only one I 
can see available in the lab.
