These calls should be completely valid: String[] strArray = conf.get(String[].class, "strings"); Integer[] integerArray = conf.get(Integer[].class, "integers"); int[] intArray = conf.get(int[].class, "ints"); ... and I have implemented something like this in the past. Method getArray should be deprecated immediately. Especially if it is not possible to use it in a type-safe way.
