My config: Hudson 1.333 (was 1.328) running under Winstone, WinXP Pro SP3
master, 3 linux slaves, 13 total executors YEAH.

Multiple people including myself have found a problem with the update center
after upgrading to 1.333. In each case, there are no updates or available
plugins shown.

If you go to the advanced tab and try to reload with "Check now", in my case it
just sits on the "Checking Updates..." screen. But, immediately in the out logs
you get errors like what I have pasted below. Others have reported similar stack
traces, though the json error doesn't occur at the same character every time.

I tried deleting the update-center.json file to no avail. It is not recreated
after I do the "Check now" feature, though the time last updated itself seems to
update.

My log output.. seems to indicate a massive query string coming into winstone.
Could be hitting the limit for query string of a GET request. If you take just
the query string snippet it complains about in the first log statement, it is
4097 characters. May be hitting the magic number. I'm using Firefox 3.5 and I
think its limit on the query string is 4k. It used to be anyway. Could also be
WinStone's limit.
