Each request is registered with an MBean in the MBeanServer. As long as the request is running, the MBean contains additional info, like the URI, when the request started, the thread name etc. This gives you enough info to find long running requests and to find the thread. But there's no non-deprecated Java API known to have no side effects to terminate a thread. If it were (or you find one), we had to check how the thread pool behaves w.r.t. "vanishing" threads.
