The placeholder is there because otherwise, some part of Hibernate
EntityManager's configuration bootstrap complain.

But this value should never be used because Hibernate OGM has an
integrator that overrides the ConnectionProviderInitiator with a Noop
The fact that Sergio's stacktrace shows 

Caused by: org.hibernate.service.jndi.JndiException: Unable to lookup JNDI name [---PlaceHolderDSForOGM---]
        at org.hibernate.service.jndi.internal.JndiServiceImpl.locate(JndiServiceImpl.java:68)
        at org.hibernate.service.jdbc.connections.internal.DatasourceConnectionProviderImpl.configure(DatasourceConnectionProviderImpl.java:116)

is proof to me that the OgmIntegrator is not taken into account which
means that the file
is not seen by Hibernate ORM when it bootstraps the application which
means that Hibernate OGM's classpath is not visible where it should be.

That's why I strongly suspects that this is either a JBoss modules bug
or some misconfiguration of the ogm modules.

We could try and give a better error report, open an issue for that but
at the end of the day, something is broken in the ORM-AS integration wrt
integrator and service discovery.
