You can use a properties file. Afaik, there's no problem with them and they are fully supported. Config files with typed properties will be supported through KARAF-5074 <https://issues.apache.org/jira/browse/KARAF-5074> which is a new feature.
For the location attribute, a new JIRA would be required. But if you're planning to use typed config files and use that attribute as a work around, that's a bad idea, as other parts of Karaf will not support it. Btw, if you want to speed up things a bit, as you seem quite vocal, one way would be to provide some patches. 2017-04-03 18:41 GMT+02:00 CLEMENT Jean-Philippe < jean-philippe.clem...@fr.thalesgroup.com>: > Hi, > > > > The issue KARAF-4829 was closed.
