AFAIK no servlet runners explicitly unload your servlets.
The most common (only?) behaviour for a servlet runner is:
when a servlet is invoked the servlet runner checks the servlet's class
file to see if it has changed since the servlet was loaded. If the class
file was changed the servlet runner creates a new servlet class loader and
the new class loader loads the new servlet.
The old servlet instance is potentially still loaded waiting to finish up a
thread or whatever. The old servlet instances may be garbage collected when
nothing is holding a reference to them anymore (e.g. at least all threads
are complete etc. ) Of course given how garbage collection works the old
servlets may never be garbage collected until you servlet runner wants to
shutdown.
