Odd behavior of SimpleDateFormat

Code:

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("YYYYMMdd", Locale.US);
Object o = simpleDateFormat.parse("20111216");
System.out.println(simpleDateFormat.format((Date)o));

Output

20111226

Why? Giant bug?

I think the greater question hinted by the op on this has been missed.

Why is it that sometimes 'Y' works despite the docs. Yes it should be 'y', but on some systems 'Y' works.

I developed on a mac where 'Y' worked and it blew up on prod Linux where 'Y' didn't work. Not hard to realize what's going on, but very annoying.

Once I fix the pattern (it should be yyyyMMdd with lowercase y), the code works as expected (it outputs 20111216).
