[hibernate-dev] Discovering/configuring package-info
Trying to upgrade to 4.3-SNAPSHOT, the EntityManagerFactoryBuilderImpl.indexResource() is
failing for my persistence.xml configuration in Java SE with
Persistence.createEntityManagerFactory():
<persistence-unit name="SimplePU">
<jta-data-source>myDS</jta-data-source>
<class>org.jpwh.model</class>
<class>org.jpwh.model.simple.Item</class>
<class>org.jpwh.model.simple.User</class>
<class>org.jpwh.model.simple.Bid</class>
<class>org.jpwh.model.simple.Address</class>
<class>org.jpwh.model.simple.Category</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
</persistence-unit>
The <class>org.jpwh.model</class> was necessary in 4.1 to get the
package-info.java of that package included, it contains my @GenericGenerators.

It looks like the only way to currently get package-info picked up is with automatic
scanning. But in my case scanningContext.isDetectClasses() is false…
