What is a Cartridge Group in Stratos 4.1.0?

[Shaheedur Haque (shahhaqu)]

Hi,

I am trying to define the application shown below, but am getting this 
exception:

TID: [0] [STRATOS] [2015-03-17 10:09:21,282] ERROR 
{org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver} -  Cartridge group 
not found: [group-name] blade-0x0
java.lang.RuntimeException: Cartridge group not found: [group-name] blade-0x0
        at 
org.apache.stratos.autoscaler.applications.parser.DefaultApplicationParser.parseGroups(DefaultApplicationParser.java:563)
        at 
org.apache.stratos.autoscaler.applications.parser.DefaultApplicationParser.buildCompositeAppStructure(DefaultApplicationParser.java:315)
        ...

I'd not heard of a cartridge group, so I Iooked in  
https://docs.google.com/document/d/1AYLAAXySvh24JZw0NQixlKg4yX8jqD3Vtc_Pz-zmHaw,
 only to see a (new?) reference to such an object, with no data. I eventually 
found 
https://cwiki.apache.org/confluence/display/STRATOS/4.1.0+Sample+Cartridge+Group+Definition.
 However, ignoring the obvious errors/obsolete items, this seems completely 
redundant w.r.t to the Application definition. So what is this object for? How 
do I get rid of the error?

Thanks, Shaheed

P.S. This is the Application, note that "blade-0x0" is in the outermost group, 
and the output is sorted by key:
