Have you tried to restart your dev server?
One possibility is that your events(when you modify jsp, event should be triggered) are getting blacklisted by event admin try to white list them
Also make sure you clear browser cache.
Try opening it in incognito window of the browser.
I hope this will work for you.
Thanks and Regards
Also you can try clearing of the temporary folders/files related to your project. generally the folders are as below.
Any updates? It is working now ?
