Hello,

I read in the docs in section 12.1.4 (http://www.hibernate.org/hib_docs/v3/reference/en/html/transactions.html) that the session stores all persistent objects - which means the objects returned by queries.
I feel this a problem in case of the session-per-application-transaction pattern as well because the session can grow very large.

My q.: why not create a method in Session which discards non-dirty objects from its cache? Am I misunderstood something?

Regards,

because those non-dirty objects may be referenced by dirty objects . when the session is flushed, you would get a pretty stack trace along the lines of "object references null or tranisent value".

use Session.clear or Session.evict if you have memory probs
