Hibernate cannot process package-info.java any more

I tried the snapshot which contains Hibernate 4.3.0.Beta2. However, package-info.java files are causing problems. For instance, the package de.shop.artikelverwaltung.domain has a package-info.java which causes a NoClassDefFoundError:
"IllegalName: de/shop/artikelverwaltung/domain.package-info". Please see the stacktrace below.

Here is an example for package-info.java which was working with WildFly 8.0.0.Alpha1:
@XmlAccessorType(FIELD)
@Vetoed
package de.shop.artikelverwaltung.domain;
import static javax.xml.bind.annotation.XmlAccessType.FIELD;
import javax.enterprise.inject.Vetoed;
import javax.xml.bind.annotation.XmlAccessorType;

The stacktrace:
