They are using Adobe ColdFusion which prior to version 10 was using JRUN as the JVM. Adobe doesn't even support nor let you download version 9 and below anymore. Granted there are a couple hiccups moving from 9 to 10 but mostly (and understandably) it involved if you were calling Java directly. For the most part its pretty painless to upgrade.
