Name and version of the database you are using:

MySQL 5.0.27

Possible Explanation:

I'm using tapestry-hibernate 5.0.5. The Session is injected automatically. It is an instance of org.hibernate.Session. In org.hibernate.search.impl.FullTextSessionImpl, it tries to cast org.hibernate.Session to org.hibernate.classic.Session and thus ClassCastException results.

Yes Hibernate Search needs a Session object that implements:
- o.h.classic.Session
- o.h.event.EventSource
- o.h.engine.SessionImplementor
Those 3 are implemented by the SessionImpl object

so either tapestry has to provide an Hibernate Search integration, or a way for you to access the underlying session object (not the proxy).
