The STM interface was meant to make servlets thread-safe by making sure that no two threads ran the same servlet instance at the same time. But over time it became clear that this is not sufficient to make web apps thread-safe; there are other concurrency issues (having to do with sessions and context attributes). So it was decided to abandon this nonfunctional approach to thread safety. The burden to make web apps thread-safe now lies solely with the application developer.
