Greenhopper is unavailable since the ugprade task is failed, see following error:

      2013-03-21 07:45:07,751 http-apr-8080-exec-15 ERROR vkharisma@awesome.com 465x1147x1 12tabsn 172.21.140.111 /rest/plugins/1.0/com.pyxis.greenhopper.jira-key [sal.core.upgrade.DefaultPluginUpgradeManager] Upgrade error: Unexpected exception caught during plugin upgrade: java.lang.NullPointerException

      This is due to the upgrade task is not successfully convert mix-case username hence makes it NULL

                ...
                // make it lower case - we hope "unassigned" is already ok...
                String assignee = cardColorAO.getVal();
                String lowercasedAssignee = IdentifierUtils.toLowerCase(assignee);
                if(!assignee.equals(lowercasedAssignee))
                {
                    cardColorAO = ao.get(CardColorAO.class, cardColorAO.getId());
                    logInfo("Changing card color assignee from '%s' to '%s'", assignee, lowercasedAssignee);
                    cardColorAO.setVal(lowercasedAssignee);
                    cardColorAO.save();
                ...
      

      There are NULL values in the "60DB71_CARDCOLOR" below:

      "#cccb6b" 335 1 19 "assignee" ""
      "#8d6811" 336 0 19 "assignee" ""
