I haven't tested this out, but from the plugin documentation < http://logging.apache.org/log4j/2.x/manual/plugins.html>, if you make a plugin that implements Collection, then you can automatically convert its children into that collection. In that use case, though, you'd need another plugin element for your validPackages list instead of a plain String.
There's no built-in TypeConverter for arrays (other than byte[] and char[] which have special meaning anyways), so another alternative would be to add a TypeConverter for Collection<String> or similar, though reifying generics at that point for more general Collection<T> usage would become an exercise in frustration IMO.
