      Description

      When a client disconnects the following exception is showing up in the server console's stdout

      (It is unclear to me atm whether we should add a check for null session in LdapRequestHandler.handleMessage() or we can handle it in a better way before reaching the LdapRequestHandler)

          This exception doesn't seem to show up in the logging when I configure log4j with:

          log4j.logger.org.apache.directory.server.core.authn=DEBUG

          Have placed a null check before processing the message in LdapRequestHandler.handleMessage().
          Please reopen if this is not the right place or if [1] is not right fix
