[jira] [Commented] (DISPATCH-1836) Policy config file 'vhost'
parsing fails; diagnostic message is poor
[ https://issues.apache.org/jira/browse/DISPATCH-1836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17231795#comment-17231795 ]
Charles E. Rolke commented on DISPATCH-1836:
--------------------------------------------
Issue https://issues.apache.org/jira/browse/DISPATCH-1659 proposes deprecating the conf-file format in favor of pure json.
Originally the conf-file format did not allow for specification of maps nor for embedded maps. This issue (DISPATCH-1836) arises due to the failure of the conf-file processor to correctly extract the pure-json vhost specification embedded in the overall conf file.
