I uninstalled java today by using this guide.
Since then I get an dialog which asks me for installing java. This happens every time after a login to my user. How can stop this request or how I can determine why I get this requests?
Check your login items (System Preferences → Users & Groups → Login Items). If it's happening on every login, it's likely you have some process that requires Java in your login items.
If you can't find an explanation amongst login items then you could begin with a log in as a different user, and command:
sudo execsnoop -v
Then log in as the user with the Java puzzle and note the time of appearance of the dialogue.
Switch to the first user, Command-C to abort the run of
execsnoop then consider the time range before the dialogue appeared.
