Hi
I just installed xwiki 0.9.840, my environment is Tomcat 5.5.9 and MySQL 5.0.15 with the
latest JDBC-Connector. I got the following exception. I searched around but did not find a
solution.
Any ideas ?

AssertionFailure:<init>:22 - an assertion failure occured (this may indicate a bug
in Hibernate, but is more likely due to unsafe use of the session)
