Is AnnotationConfiguration serializable?

My application has a lot of classes mapped with annotations and it takes over 6 minutes to start up in a given (old) computer.

I read in this forum that Configuration is serializable but couldn´t find anything about AnnotationConfiguration. In my case it is not working.

I´m using hibernate-annotations-3.2.0.CR1 and hibernate-3.2.0.cr2

Here is the stacktrace:

org.hibernate.type.SerializationException: could not serialize
at org.hibernate.util.SerializationHelper.serialize(SerializationHelper.java:158)

Caused by: java.io.NotSerializableException: org.hibernate.cfg.EJB3NamingStrategy

Still appears unserializable under hibernate-annotations 3.2.0.ga and hibernate 3.2.0.ga?

Code:

I cannot reproduce, can you attach a failing test case (minimal) to a JIRA issue.

Besides, your line numbers, looks odd for 3.2.0.GA

year, I did not know you were actually using our helper class in your code.
