I don't think we can do better at this point.  There is no limit on the 
complexity of attribute values, and the only restriction other than 
serializablitly is that classes used must be loadable by the 
configuration's classloader.  This classloader is only available when 
the configuration gbean is started.

If you're willing to use the kernel methods directly rather than the 
methods on ConfigurationManager (I recommend sticking to using the 
ConfigurationManager) you could pass your own ManageableAttributeStore 
in that gets all the gbean datas and return an empty list.  This would 
result in you getting the gbean datas and no gbeans getting loaded.

Why do you want to avoid loading the gbeans?
