I am trying to configure Hibernate 4.1.9 with EhCache 2.5.2.
It was working fine as long as i used net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory
But i have multiple session factories in my application.
So i shifted to using net.sf.ehcache.hibernate.EhCacheRegionFactory
Now i get the exception
Another unnamed CacheManager already exists in the same VM.

I had solved this issue on hibernate 3.5.2 by setting different names
in net.sf.ehcache.cacheManagerName property for each instance of EhCache
Same thing doesnt work on hibernate 4.1.9

Has anyone tried this combination ?
