RE: [Hibernate] Caching of collections

[Gavin King]

OK, but you do realize that this is the Hibernate development mailing list, not the JavaRanch beginner forum, right?   We already know all about concurrent.jar. ;-)   From: Lane Sharman [mailto:[EMAIL PROTECTED]] Sent: Thursday, 12 May 2005 1:34 AM To: Gavin King Cc: hibernate-devel@lists.sourceforge.net Subject: Re: [Hibernate] Caching of collections   You stated "there are some subtle concurrency issues" and that was what I keyed off on. I observed that we found Doug Lea's code extremely helpful in dealing with concurrency issues between a memory image and a persistent image across multiple threads. Since apparently this does not apply, I will not make suggestions like this in the future.
