I get the following exception on running my application.
I believe some versions of ehcache jars are not compatible with hibernate-3.2 jar.
I have tried all permutations and combination by changing the versions of both the jars, still it doesn't seem to work.
Looks like either a classloader or a jar version issue.
I am running hibernate-3.2.6-ga.jar and it does indeed reference net.sf.ehcache.CacheManager from the org.hibernate.cache.EhCacheProvider class. My version of ehcache is ehcache-1.4.1.jar, and they seem to be happily getting along.
