Hi,
We had an issue in our project where large hql expressions holding on lock to
ChangeAwareClassloader in weblogic.
We had an hql query which was like
select * from ClassA a where a.identifier = 'id1' or a.identifier='id2' or
..... a.identifier='id1000'.
This was certainly bad to have this big or expression, but an issue this caused in
weblogic is something interesting.
Hibernate query engine processes each identifier in a query to see if its a Java Class. So
for each one of ClassA, a.identifier etc it calls Class.forName, if NoClassDefFound
exception is thrown, ReflectHelper.getConstantValue returns null.
Now the problem is, if the expression is huge, recursive calls to
/NodeTraverser.visitDepthFirst create huge stack trace. While building
ClassNotFoundException, system class loader gets stuck to build all this stack trace.
Because weblogic/utils/classloaders/ChangeAwareClassLoader.loadClass method is
synchronized, any other thread trying to load any other class is blocked. If the stack
trace is huge and taking consideratble amount of time to create Exception object, the lock
is held for that much time, blocking every other thread trying to any the class. It
brought down our servers in test environment.
Is this a known issue in weblogic and hibernate? I know that building such a large
expression is bad(and we have already changed the code which was doing that), but the way
its blocking the classloader in weblogic is an issue I think.
Following is the thread dump.

New subject: large hql queries holding classloader lock for too long in weblogic
Umesh,
This is good information but it should be raised on the user forum or
perhaps filed as a JIRA with a test case. This list is for discussion
of the development of Hibernate (not *using* Hibernate).
Cheers,
Chris

The way this constant check occurs is much different in the new code on
which I am working right now. The code you are looking at (the
visitation) was a band-aid. The better way to do it is as part of the
tree building which is what happens now.
The recursive descent here is known to be problematic in a few
situations. For example, another is that it can lead to stack overflow
exceptions even if the recursion is not infinite. Not to mention that
it is really just unnecessary overhead provided the constant recognition
can be achieved in building the tree.
