Axel Wilhelm Berle · **Posted:** Sat May 20, 2006 9:08 pm

I am trying to migrate my 3.1 app to 3.1.3 but encountered a strange migration issue (yes, I read the migration page).

When making some database queries, I get a StackOverflow:

Code:

Caused by: java.lang.StackOverflowError
        at java.lang.reflect.InvocationTargetException.<init>(InvocationTargetException.java:54)
        at sun.reflect.GeneratedMethodAccessor52.invoke(Unknown Source)
        at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
        at java.lang.reflect.Method.invoke(Method.java:585)
        at org.hibernate.jdbc.BorrowedConnectionProxy.invoke(BorrowedConnectionProxy.java:40)
        at $Proxy0.getAutoCommit(Unknown Source)
....

I am clueless, please help!

Hi,

I am having the same problem occur intermittently. Did you find a solution for this?

Hi,

the problem was related to the HibernateFilter which I used to implement long-running application transactions. When I switched to HibernateThreadExtendedFilter (and the new HibernateUtil) as shown in the CaveatEmptor example it works fine. Beware though for the missing synchronization issue. You should syncronize on the HttpSession object. The best solution is to synchronize on some object that you put into the session.

Hope this helps!
