S2hibernate plugin is incompatible with latest hibernate validator 4

I get the following error:

java.lang.ClassNotFoundException: org.hibernate.validator.InvalidStateException

This is because this exception is now deprecated i believe.

You can see it in the javadocs for version 3: http://docs.jboss.org/hibernate/validator/3.x/api/index.html? org/hibernate/validator/InvalidStateException.html

But in the latest version of hibernate it isn't there: http://docs.jboss.org/hibernate/stable/validator/api/index.html? org/hibernate/validator/package-summary.html

Please help, thanks.

Can be the same problem of issue 13
