Haha meatpuppetry. And after several corrections some of them are still referring to Spring as a game, and not as an engine. I almost thought that they might have had a legitimate case until I saw some of the comments. Anyway smoth is right, wikipedia is fail, not really worth it to try to keep an article on there.
Something else interesting, from a quick glance at this list
I would say that almost all of the free/open source engine articles are "not notable". In fact, probably very few open source projects would pass their "standards", which is bitterly ironic considering that open source was the spirit that birthed wikipedia. Oh well, thats what they get for letting people who get off on having control run amok on their website.
