Couple of OSAccess errors

I'm trying to setup an osaccess test, but am getting three errors:

SEVERE: Could not init provider

property acls in class
com.opensymphony.module.access.provider.hibernate.resource.Resource
	at net.sf.hibernate.util.ReflectHelper.getSetter(ReflectHelper.java:138)
	at ...

and:

[ERROR] com.opensymphony.module.access.config.ConfigLoader : Could not
initialize provider
com.opensymphony.module.access.provider.hibernate.HResourceProvider

and:
