JPA PersistenceUnitInfo.persistenceUnitRootUrl vfs URL should be resolved

Wildlfy passes a PersistenceUnitInfo object to JPA provider using vfs URL as persistenceUnitRootUrl, e.g.,

    vfs:/C:/wildfly-20.0.1.Final/bin/content/foo.ear/myejb.jar/

A JPA provider can not resolve this URL without using a third-party library and thus force

the JPA provider to have dependency on 3rd party libraries or wildfly.

The vfs url should be resolved to a plain file or jar URL that actually exists on file system before passing the URL to a JPA provider when creating an EntityManagerFactory.
