Hi all.
My working app were using hib 2.0.3 and spring 1.0-m2
After upgrading to hibernate 2.1 and spring 1.0.2
it stopped working, throwing exception
during the init phase.
exception is as follows, and stepping into the hibernate code,
it is thrown at the line:

QUERY_KEY_FACTORY = (QueryCacheKeyFactory) KeyFactory.create(QueryCacheKeyFactory.class);

line 235 of file net.sf.hibernate.impl.SessionFactoryImpl;

I'm wondering what is wrong since applicationContext file
was not changed in the meanwhile, nor the hbm.xml files

Could someone please to the right direction
to address waht the problem is?

best regards,
davide
