but it throws RTEs at you anyway :)

public static T[] convertPrimitiveArray(final Object array, Class wrapperClass) {
final int arrayLength = Array.getLength(array);
final T[] result = (T[]) Array.newInstance(wrapperClass, arrayLength);
for (int i = 0; i < arrayLength; i++) {
Array.set(result, i, Array.get(array, i));
}
return result;
}
