I'm using hibernate 4.3.5.Final (using maven dependencies, and using Tomcat 7.0.47).

Like

  <persistence-unit name="com.iorga.irajblank" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    ...

But I'm getting

avr. 24, 2014 5:01:24 PM org.hibernate.ejb.HibernatePersistence logDeprecation
WARN: HHH015016: Encountered a deprecated javax.persistence.spi.PersistenceProvider [org.hibernate.ejb.HibernatePersistence]; use [org.hibernate.jpa.HibernatePersistenceProvider] instead.

I've seen that hibernate-entitymanager-4.3.5.Final.jar/META-INF/services/javax.persistence.spi.PersistenceProvider contains those lines :

org.hibernate.jpa.HibernatePersistenceProvider
# The deprecated provider, logs warnings when used.
org.hibernate.ejb.HibernatePersistence

But as in hibernate-jpa-2.1-api-1.0.0.Final.jar:javax.persistence.spi.PersistenceProviderResolverHolder.PersistenceProviderResolverPerClassLoader.CachingPersistenceProviderResolver.loadResolverClasses(ClassLoader) those ones are added in a HashSet (using addAll method), when listing them (in hibernate-jpa-2.1-api-1.0.0.Final.jar:javax.persistence.Persistence.getProviders()), org.hibernate.ejb.HibernatePersistence is listed first.
