Hi You wrote, that when an application is unloaded, that tomcat discards all references to the classes of that web application, therefore the garbage collector could effectively "unload" that application.
However, there are web applications that have own threads (file reaper, connection pool, etc.). That means that there is no real way to safely unload a web application. I am thinking about a strategy to iterate over all running threads and interrupt (and if absolutely necessary stop) all threads started by a certain classloader (not sure if it is possible, but I suspect so - might require instrumention though.)

I don't understand your comment; Thread objects always exist, and what do you think that has to do with unloading classes? - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
