FYI, there's a reasonable way to do this in Guava without Java 8:

ImmutableSortedSet set = ContiguousSet.create(
    Range.closedOpen(0, 7), DiscreteDomain.integers());
ImmutableList list = set.asList();

If you don't actually need the List semantics and can just use a NavigableSet, that's even better since a ContiguousSet doesn't have to actually store all the elements in it (just the Range and DiscreteDomain).
