[udig-devel] Too many plug-in apis in the kitchen?

[Jody Garnett <jgarnett@xxxxxxxxxxxxxxx>]

I am having a wee bit o fun with Eclipse vs Geotools and their ideas on 
extendability.

Near as I can tell:
- eclipse does a bunch of magic class loader stuff (to keep plugins in 
separate Class loaders) unless they explictly have a common dependency.
- geotools does some magic lass loader stuff when locating a 
DataStoresFactorySpi for use

Here is the error message:
org.geotools.factory.FactoryConfigurationError: Provider 
org.geotools.data.gml.GMLDataStoreFactory not found - please check your
