Eclipse Neon: Http Preview Server no longer working after Upgrade

edit

Hello,

I recently upgraded from F23 to Fedora 24 using the dnf-system-upgrade plugin.

During the system upgrade the eclipse mars I had used was replaced with the newer eclipse neon release.

Now the problem: When developing a web static project - only javascript, html and css - with eclipse, you can run the project as usual. But instead of starting some program eclipse starts a webserver and serves the content in the browser. The server is the Http Preview which comes build into eclipse. After the update when starting the http preview i get a popup with an error message:

Could not find required bundle javax.servlet.

Does anyone know how to solve this problem?
