Niclas Hedhman commented on QI-132:
-----------------------------------
Well, there are two reasons;
1. Arrays are part of the Java Lanaguage and it is odd if we don't support it.
2. In my case, the String's are picked up from a configuration and not changed
while the service is running and the input in the API is String[] so why
convert each time it is used...
> Property<String[]> strings(); doesn't work...
