shutdown

public static void shutdown()

WebSphere won't shutdown a servlet until after a 60 second timeout if there is an instance of the servlet executing a request. Add this method to enable a hook to notify Hystrix to shutdown. You must invoke this method at shutdown, perhaps from some other servlet's destroy() method.

init

public void init()
          throws javax.servlet.ServletException

Overrides:

init in class javax.servlet.GenericServlet

Throws:

javax.servlet.ServletException

destroy

public void destroy()

Handle servlet being undeployed by gracefully releasing connections so poller threads stop.

Specified by:
