Doc says this:
CacheMode.IGNORE -> "The session will never interact with the cache, except to invalidate cache items when updates occur"

However, Hibernate actually write items to cache when updates occur.

I'm using CacheMode.IGNORE to avoid cache size increase for a certain case, but when update occurs, cache size increases.

To reproduce this issue, just open a session and call session.setCacheMode(CacheMode.IGNORE), then load and update an item. Attatched is the complete test code. In the test code, I investigate ehcache contents to make sure what data is cached, just to clarify the issue.
