Classcast exceptions in GeneratedPackageDescriptorImpl

[rick rineholt <cr...@yahoo.com>]

I'm seeing a class cast exception in 
GeneratedPackageDescriptorImpl.getEPackage() on the
line:
 ePackage = (EPackage) eInstance.get(null);

The reason I've concluded is that many of the EMF jars
are needed in 
TC's common\lib
and they also seem to be in the samples war's
WEB-INF\lib and resulting 
in some classes being loaded by TC's
StandardClassLoader and instances 
also loaded by TC's webapp classloader.  But then
they're not the same 
class and results in a classcast exception.
Locally I've eliminated the ones in the sample's war
and the exception 
went away. I guess this can work now as a solution if
maven can be 
coerced not to package them.  But in the long run I
think webapps need 
to be able to have their version's of these jars.
