I tested your code, the init is called exactly once, when Tomcat starts.
Try one of these:
1) Change
log.info("TestServlet init");
log.info("TestServlet destroy");
to something else like
log.info("TestServlet init ############## ");
log.info("TestServlet destroy ##############");
Re-compile, re-start TC if necessary and
check if you see 2 different outputs on the console.
2) If you see the same output twice, that is if you see
log.info("TestServlet init ############## ");
log.info("TestServlet init ############## ");
log.info("TestServlet destroy ##############");
log.info("TestServlet destroy ##############");
then check web.xml if the same Servlet is defined twice under
different names.
3) Globally search for "TestServlet init" and see if it appears in
more than one Servlet that may be visible to the current installation
of Tomcat.

Do a global search on your projects and also on C: or Home drive to
see if this line of code is defined in an additional Servlet that is
visible to the current installation of Tomcat:
log.info("TestServlet init");
I know you mentioned that there's only one Servlet under webapps, but
just in case...
I also see super.init(config); but that shouldn't cause the
TestServlet's init method to be called twice.

I will try to replicate this.
