 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 ?
Yes. Ugly, but possible.

 By the way, there mightbe a NullPointerException issue while using the
 BackupManager in the HTMLManagerServlet.

Really? Where?

 args[5] = new Integer(0);
 }

   Could you please show the way, and do the devs plan to work on it ?
Thanks.
