Hello,

I'm having problems to upgrade hibernate. I have changed hibernate3.jar and included all
required jars from the lib directory. A also have updated hibernate-entity-manager and hibernate-annotations.
When I start tomcat I get the following exception:

java.lang.NoClassDefFoundError: Could not initialize class

I don't understand how this can happen because ManyToOne.java is in the same jar
and is loaded without problems.
I have checked TypeFactory.java and found out the following:
- All included packages are either part of java or hibernate, there are no external dependencies.
- There is a static initialization block.

Thanks,

Max
