I have a maven application that works fine in wildfly 8.2, but when Ideployed it in wildfly 10 this error happened:

Had the same problem, but I solved it using the hibernate5 official quick start available here https://github.com/wildfly/quickstart/tree/11.x/hibernate5

Try the hibernate5 quick start, it should work.

Have a look at the pom.xml, it contains

    
        org.hibernate.javax.persistence
        hibernate-jpa-2.1-api
        provided
    

    
    
    
    
        org.hibernate
        hibernate-validator
        provided
        
            
                org.slf4j
                slf4j-api
            
        
    

    
    
    
        org.hibernate
        hibernate-core
        provided
    

Include that and it will work. I had to undeploy my app and restart wildfly.

If you need to use another Hibernate version than the one provided in Wildfly, follow the official procedure to update the Hibernate version in Wildly, section Replacing the current Hibernate 5.x jars with a newer version.
