Where's all this light coming from?

My very simple hostile mob spawner has a slight problem. The problem being that the mob spawner doesn't spawn mobs. The basic idea was to have a huge cobblestone box, in which mobs would spawn, fall into a central hole (with the help of water, and then be killed at the bottom.

However, I can't seem to get rid of this strange light in the spawner. There are no torches around; I have checked thoroughly. In fact, the light seems to be coming from the water source blocks. The odd thing is, whenever I force one of the water blocks to update, the light goes away, but when I close up the box and open it again, the water starts glowing again. In any case, nothing spawns.Light-up water‽

@Resorath That question didn't seem to explain why it was happening. In addition, that applied to light sources in the water, of which I assure you I had none. Thanks though. – Istvan Chung Dec 15 '11 at 18:49

This is a known bug¹ in Beta 1.8 which was reportedly fixed in the Beta 1.9 prereleases prior to the official release.

¹ Apologies for the non-official source; I'm at work and can't access the wiki to see which page it's listed on.

Minecraft Wiki is not especially “official” — it just has lots of people editing it. I say this as one of those editors: Don't assume it's correct. – Kevin Reid Dec 16 '11 at 12:05
@Kevin Reid — Jeb is known to work from the wiki's bug list, which I'd say makes it closer to official than anything else we've got. :-) – Ben Blank Dec 16 '11 at 15:19
