* non-unit-dependent properties. Effectively, this PersistenceUnitInfo-based
* variant only needs to be implemented if there is an actual need to react
* to unit-specific characteristics such as the transaction type.
* <p><b>NOTE:</b> This variant will only be invoked in case of Java EE style
* container bootstrapping where a {@link PersistenceUnitInfo} is present
* (i.e. {@link LocalContainerEntityManagerFactoryBean}. In case of simple
* Java SE style bootstrapping via {@link javax.persistence.Persistence}
* (i.e. {@link LocalEntityManagerFactoryBean}), the parameter-less
* {@link #getJpaPropertyMap()} variant will be called directly.
* @param pui the PersistenceUnitInfo for the current persistence unit
* @return a Map of JPA properties, as accepted by the standard JPA bootstrap
* facilities, or an empty Map if there are no properties to expose
