   > Service A and B have same interface com.test.InterfaceXXX, their 
dubbo.application.metadata-type are same local, but group or version are 
different,
   > Consumer C only invokes com.test.InterfaceXXX of service A, the connection 
between C and A is allowable, but the connection between C and B is forbidden 
by firework.
   > When consumer C created dubbo reference of service A, it will get mapping 
metadata which mapping key is com.test.InterfaceXXX, of course the result from 
metadata center has both A and B
   > Consumer C will try to connect to both A and B to building reference of A 
(their metadata-type are both local), but it will be always failure because the 
firework will break down the connection from C to B.
   
   Was Consumer C consuming services of all versions and groups with 
`group="*"` and `version="*"`? Can we just change Cosumer C and tell it to only 
consume service instances of certain group and version, this can make it simple.
