bug from AS rails tests

Seems to related to #1769

# jruby master
irb(main):002:0> require 'date'
=> true
irb(main):003:0> Date.new(1581,10,10).next_year
=> #<Date: 1582-10-20 ((2299166j,0s,0n),+0s,2299161j)>

# ruby 2.2.2
irb(main):002:0> require 'date'
=> true
irb(main):003:0> Date.new(1581,10,10).next_year
=> #<Date: 1582-10-04 ((2299160j,0s,0n),+0s,2299161j)>

This could be simple so I'm marking for beginners.

It seems like a good bug to get started.
@eregon had already posted a solution at #1769, but he also mentioned that it's likely to be fairly slow.
@headius Let me know if you have something like that in your mind.

I'm not concerned about the performance if we can get a fix in for this for JRuby 9k RC2. @eregon or @raeoks, can you make a PR so we can wrap this up?

I'll let @raeoks take care of it since he already worked on adding tests/specs.

@eregon It's been a pleasure to work on JRuby. Next I'll move on to another beginner bug.
