strg+click doesn't work with sts for variables - spring-tool-suite

Question

This is a issue which bother me a long time.
Now i found the solution so i wanted to share it.
When i open a class in the editor i got the problem that the navigation to the declaration of a class, method is working, but when i want to navigate to a the declaration of an variable it doesn't work.
I also discovered that this problem is happening with sts 3.6.4.RELEASE and also with 3.7.0.RELEASE.
After some investigation i found this stacktrace in my sts logs.
java.lang.NullPointerException

Answer 1

The solution for this is to go to
General -> Editors -> Text Editors -> Hyperlinking
and to deactivate "Autowire Hyperlink Detector".
