You can also set jboss.as.jpa.managed=false in the persistence unit, 
which avoids the EE bootstrapping of the persistence unit.

I'm not sure if 
https://docs.jboss.org/author/display/WFLY10/Spring+applications+development+and+migration+guide 
is up to date but that mentions using jpa-persistence.xml instead of 
persistence.xml (via Spring LocalContainerEntityManagerFactoryBean 
settings).
