I am trying to deploy application that uses Hibernate 4 on EAP 7. When the application is deployed, JPA entity auto scan does not detect any entity classes.

From what I managed to discover, the issue is with the org.hibernate.jpa.boot.archive.internal.JarInputStreamBasedArchiveDescriptor. Inside the visitArchive method there is the following code fragment:

jarInputStream = new JarInputStream( getArchiveUrl().openStream() );

The input stream does not contain any data and the:

while ( ( jarEntry = jarInputStream.getNextJarEntry() ) != null ) { .. }

loop never executes because there are no jar entries. I believe the issue is somehow related to VFS and the VirtualJarInputStream.

I attached a sample Maven Eclipse project. It should fail with the Caused by: java.lang.IllegalArgumentException: Not an entity: class org.jboss.tools.examples.model.Member exception.

The same issue exists on Wildfly 11 too.
