[ JDK VERSION : 1.5.0_02 ]

Although compilation cpk,[;etes without errors, attempts to rename my local variable q2 fail with the following error:

"The original element being refactored is not available.  It was deleted or signficantly changed.  Usages can not be collected."

The IDE log contains no exceptions.

Source in question is 

public int getTodaySize() throws CobblerException {
        String q2 =   "select sum(sf.size) from SourceFile sf where audited = true and sf.project = :project and changedate like :today";
        Session session = Setup.getSessionFactory().openSession();
        Integer lines = (Integer) session.createQuery(q2)
            .setLong("project", getId())
            .setString("today", "2005-05-19")
            .uniqueResult();
        session.close();
        return lines == null ? 0 : lines.intValue();
    }
