Ivan Malygin commented on HHH-1283:
-----------------------------------
I'm also confirming the bug. I think this bug, because it makes Criteria API useless for the cases with one-to-many relations.

[Hibernate-JIRA] Created: (HHH-3442) StaleObjectStateException logs unnecessary stacktrace
by Tom van den Berge (JIRA)
StaleObjectStateException logs unnecessary stacktrace
-----------------------------------------------------
Key: HHH-3442
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3442
Project: Hibernate3
Issue Type: Improvement
Affects Versions: 3.3.0.GA
Reporter: Tom van den Berge
Priority: Minor
When using optimistic locking, and stale state is detected, a StaleObjectStateException is thrown. This exception is caught in AbstractFlushingEventListener, logged as error, including a stacktrace, and then thrown again.
It would be better not to log the stacktrace in this situation, since it's up to the client code to deal with the exception. If the client code doesn't handle optimistic locking exceptions, it can choose to log the stacktrace itself, or otherwise do something useful with the exception, such as retrying. Currently, the stacktrace is always logged by Hibernate, also if the client code recovers from the exception, which is a bit confusing when looking at the logs.
Also the fact that this particular exception is logged with severity ERROR is inappropriate. It's up to the client code to decide if it's an error.
I suggest the following change to AbstractFlushingEventListener:
Current code:
catch (HibernateException he) {
log.error("Could not synchronize database state with session", he);
throw he;
}
Suggested code:
catch (StaleObjectStateException e) {
log.warn("Could not synchronize database state with session", e.getMessage());
throw e;
}
catch (HibernateException he) {
log.error("Could not synchronize database state with session", he);
throw he;
}

[Hibernate-JIRA] Created: (HHH-3388) Problem mixing implicit and explicit joins - Ok in Hib2 not in Hib3

Problem mixing implicit and explicit joins - Ok in Hib2 not in Hib3
-------------------------------------------------------------------
Key: HHH-3388
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3388
Project: Hibernate3
Issue Type: Bug
Reporter: Philippe Chaléat
Trying to migrate a rather large app from Hibernate 2.1 to Hibernate, we face a blocking problem. With Hibernate 3, some of our queries generate invalid SQL. I found in the forum that this problem has been noticed by someone else (but no answer) :
http://forum.hibernate.org/viewtopic.php?t=963196&highlight=join+ora00904
We manage to reproduce the problem with the following query. With Hibernate 2, mixing explicit and implicit joins produced an SQL query with all "theta style" joins at the end of the query. In Hibernate 3, ANSI and "theta style" are mixed, which Oracle doesn't like.
HBM:
select a.description, a.seller, b.item.description " +
"from org.hibernate.auction.AuctionItem a inner join a.bids b
[java] SQL:
[java] select
[java] auctionite0_.description as col_0_0_,
