Description

Support for array values encoded as strings inside of .config files is broken in given Karaf versions. Reasons for that are different between them as Karaf 4.0.10 uses new version of fileinstall, however result is the same - config values are always strings regardless of correctness of value notation. Karaf 4.0.8 and 4.0.9 in general are broken due to bug in fileinstall or config admin as they tend to override source configuration with some partia representation malformed by configuration parser.
For karaf 4.0.10, even if it uses fileinstall 3.6.0 there is no way, so far - to force configuration to be typed.
