Recursive dependency between the tomcat-catalina-ha and tomcat-catalina

[Ivan]

Hi,
    From the pom file of tomcat-catalina-ha, it depends on the
tomcat-catalina. But one class HTMLManagerServlet in the tomcat-catalina has
a reference to a class BackupManager in the tomcat-catalina-ha.  Is there a
way to remove the recursive dependency between those two components ?
    By the way, there mightbe a NullPointerException issue while using the
BackupManager in the HTMLManagerServlet.
    ---> line.523
     Manager manager = ctxt.getManager();
                if (manager instanceof BackupManager && showProxySessions) {
                    args[5] = new Integer(

((BackupManager)manager).getActiveSessionsFull());
                } else if (ctxt.getManager() != null){
                    args[5] = new Integer(manager.getActiveSessions());
                } else {
                    args[5] = new Integer(0);
                }

     thanks.
