The JPA subsystem captures the Hibernate statistics, only if Hibernate 
statistics are enabled (each persistence unit has its own statistics).

You can enable the statistics (off by default) with the following or you 
can include a (application) persistence unit property to enable the 
Hibernate statistics:

:write-attribute(name=enabled,value=true)

Address is 
/deployment=DEPLOYMENTDeterminedAddress/subsystem=jpa/hibernate-persistence-unit=ApplicationScopedPersistenceUnitName

See http://fpaste.org/52218 for example of 
/deployment=2lc.jar/subsystem=jpa/hibernate-persistence-unit=2lc.jar#TEST_PU

No, disabled by default.
