There is some conversion happening inside DS, i.e. DS will be able to
translate a single String object into a String[], but it will do so simply
by creating a single-element array. It will not do any parsing of the
content of that string.
The client of ConfigAdmin (Karaf) really needs to set the value of the
field (in the Dictionary it passes to Configuration.update) to either a
String[] or a Collection<String>. If it can't or won't do that, then I
think you have no choice but to change your component implementation to
accept a single string and parse it yourself.
