I have a problem with caching with following mapping and schemaexport:
net.sf.hibernate.MappingException: duplicate cache region
The application itself works well even with the new mapping and caching enabled (net.sf.ehcache.hibernate.Provider), but the schemaexport out of an ant task fails.
Hibernate version: 2.1.6
