Yes, there is a general servlet timeout (in servlet properties [1]) and a per
servlet
timeout in the servlet wrapper [2]. Jigsaw unload the servlets when the tiemout
is
reached.

The init method is called the first time the servlet is accessed.The init method
could be
called again if the destroy method was called or if the servlet class is
reloaded.
