    [ https://issues.redhat.com/browse/WFLY-13714?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14353906#comment-14353906 ] 

Scott Marlow commented on WFLY-13714:
-------------------------------------

Is this for a particular Java persistence provider that you care to mention?  

>From [Persistence 3.0 SPEC|https://jakarta.ee/specifications/persistence/3.0/persistence_3.0-RC2.html#a13160] which is the same as earlier JPA versions:
{code}
/**
     * Returns the URL for the jar file or directory that is the
     * root of the persistence unit. (If the persistence unit is
     * rooted in the WEB-INF/classes directory, this will be the
     * URL of that directory.)
     * The URL will either be a file: URL referring to a jar file
     * or referring to a directory that contains an exploded jar
     * file, or some other URL from which an InputStream in jar
     * format can be obtained.
     * @return a URL referring to a jar file or directory
     */
    public URL getPersistenceUnitRootUrl();
{code}

The last form can also be used ("some other URL from which an InputStream in jar format can be obtained").  

I do agree that your suggestion would be easier for the persistence provider to deal with.

> 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.
