ClassNotFoundException when class with no package used

Hibernate version: Hibernate EntityManager 3.2.0.CR1
Mapping documents:

Code:

<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm" version="1.0">
  <embeddable class="Incident$IncidentId" access="FIELD" metadata-complete="true">
  </embeddable>
</entity-mappings>

Full stack trace of any exception that occurs:

I think this is caused by the following code in XMLContext.java http://fisheye.labs.jboss.com/browse/~raw,r=10187/Hibernate/trunk/HibernateExt/metadata/src/java/org/hibernate/reflection/java/xml/XMLContext.java

Code:

   public static String buildSafeClassName(String className, String defaultPackageName) {
      if ( className.indexOf( '.' ) < 0 && defaultPackageName != null ) {
         className = StringHelper.qualify( defaultPackageName, className );
      }
      return className;
   }

It checks against null, where as in the following code, packagename defaults to "".

Code:

      //entity mapping default
      Default entityMappingDefault = new Default();
      Element unitElement = root.element( "package" );
      String packageName = unitElement != null ? unitElement.getTextTrim() : "";

Thanks,
Sahoo
