Maven pom.xml should (in time) depend on javax.persistence:persistence-api instead of org.hibernate:ejb3-persistence
--------------------------------------------------------------------------------------------------------------------

                 Key: ANN-712
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-712
             Project: Hibernate Annotations
          Issue Type: Task
    Affects Versions: 3.3.1.GA
            Reporter: Geoffrey De Smet
            Priority: Minor


Now it's possible to get the same classes (for example javax.persistence.Entity) twice in the classpath:
- one from persistence-api-1.0.jar
- and another from ejb3-persistence-1.0.1.GA.jar.
Mix that with classloaders and you get bugs like A extends B but an A is not instance of B (because B.class is loaded twice from different jars). Otherwise you can get this too, but if the groupId:artifactId match, maven deals with it.

In theory, replace:
                <dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>ejb3-persistence</artifactId>
			<version>1.0.1.GA</version>
		</dependency>
with:
            <dependency>
              <groupId>javax.persistence</groupId>
              <artifactId>persistence-api</artifactId>
              <version>1.0</version> <!-- FIXME -->
            </dependency>

It looks like org.hibernate:ejb3-persistence is just a copy of javax.persistence:persistence-api, but with a hot-fix applied to it:
probably because javax.persistence:persistence-api:1.0.1 isn't deployed to the central repo yet.
So the JCP might need to be poked to put javax.persistence:persistence-api:1.0.1 on the central repo :) Which is probably not an easy thing to do...
