      1. start EAP
      2. do configuration change 
        /system-property=foo:add(value=bar)
      3. stop eap
        history is now stored in /standalone_xml_history/current
      4. start eap again
      5. stop eap
        history is now in /standalone_xml_history/TIMESTAMP
      6. change permission of /standalone_xml_history/TIMESTAMP to 555 
        chmod 555 20170221-114800298/
      7. rename TIMESTAMP dir, change months to -2
        EAP by default deletes history older than 30 days
      8. start EAP -> boot fails

      it doesn't exactly reproduce NPE, but it shows that error while removing old config files prevents server from boot

      org.jboss.as.controller.persistence.ConfigurationFile#deleteRecursively is missing error checking.

      If an I/O error occurs while listing the directory contents (file permission error/etc) it still tries to use the listing and gets a NullPointerException.

      This method is used while removing old configuration history directories during boot, and the NullPointerException causes the EAP boot to abort.
