 Post subject: LazyInitializationException: from 3.2.0CR2 to 3.2.4.sp1

We used to run JBoss 4.0.4.GA and we included Hibernate 3.2.0CR2. Now we migrated to JBoss 4.2.2.GA and in that one Hibernate 3.2.4.sp1 is included by default.

Unfortunately, we're getting LazyInitializationException when the object graph is more than 2 levels deep.
E.g. RtTask --[OK]--> Priority --[FAIL]--> DictionaryEntry


We haven't changed anything to our beans or configuration files.

What's causing this? Is there something changed in the configuration of 3.2.4.sp1 as compared to 3.2.0CR2?

Thanks.


Nick.

I did some more testing: I replaced the Hibernate version that came with JBoss 4.2.2.GA with the latest namely hibernate3.jar (from Hibernate Core 3.2.6.ga) and hibernate-annotations.jar, hibernate-commons-annotations.jar, ejb3-persistence.jar & hibernate-validator.jar (from Hibernate Annotations 3.3.0 GA).

Unfortunately, that doesn't work either.

For now we can use the old versions but we really like to use the ones that came with JBoss. It makes it easier to migrate to newer versions of the AS when we don't have to care about Hibernate anymore. Additionally, the newer ones will have fixes for bugs that now might haunt us.

All help still greatly appreciated.

Thanks,

Nick

I did some more testing: I went through all the versions to find which one was the first to break things.
It seems that Hibernate 3 version 3.2.4.GA is the first version to throw the exception.

I checked the Hibernate JIRA site for the release (link) but I don't see anything that might have introduced the bug.

As neither our beans nor our configuration has changed, I consider this issue a bug and I'll report it in JIRA as such.


Thanks,

Nick

While creating a test case for my bug report I found out the problem was with Session.clear(). Apparently, it is a bug but unfortunately it is one of the older versions. Hibernate is suppose to throw the LazyInitializationException after using the clear()-method. (link)
Too bad we've created a lot of code that depend on this bug.
