[hibernate-dev] Discovering/configuring package-info

[Christian Bauer]

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…
