This is the case Andrea.

The DataStore API really would like to to keep them as singletons, or in 
a catalog (as uDig and GeoServer do).  There is a very
simple example in GeoTools called Registry that slurps up all the 
shapefiles in a directory. But you can do something as simple as keeping
your data connections in a java.util.Map.

I thought this was more of an issue with creating multiple concurrent 
datastores then specific problems
with WFS.
