Bootstrapping the EntityManagerFactory should log the name of the persistence unit being used [SPR-11333]

[spring-projects-issues]

Oliver Drotbohm opened SPR-11333 and commented

Assume you configure an EntityManagerFactoryBean with a packagesToScan. If the classpath contains a persistence.xml with a persistence unit name of default this one will be used instead of the one implicitly created by the package scan. This is probably a bit surprising.

While one could argue, that as soon as you configure a packagesToScan, that particular EMFB shouldn't actually look for other PUs anymore, I thing the least we should do is logging the name of the PU used eventually.
