Committed r140222: <http://trac.webkit.org/changeset/140222>
It appears this test is failing because http://trac.webkit.org/changeset/140174 causes us to prune MemoryCache a little more aggressively, leading to image.jpeg's decoded data being destroyed. I don't know a lot about this test or exactly what it's trying to verify. Yury, it looks like you wrote this test. Would it still verify the correct behavior if we used an image with a smaller decoded size?
