A servlet that cannot be initialised (an exception that occurs in the initialisation phase of the servlets lifecycle; when the container calls the init function) should throw an UnavailableException. This could for instance happen when you try to access you servelt context to retrieve some db connection .
Something like that.

But since UnavailableException is a ServletException, then we should be able to use the latter as well in place?
