Description

After upgrading from 12.0 to 12.6 (and importing the settings from 12.0), I have a StackOverflow error on each startup.

During the "background scanning of projects", an exception is thrown with this stacktrace:

(this last line is repeated around 1000 times)

 

The background scanning of projects never ends, and consumes a lot of CPU in the background

Removing the cache and restarting Netbeans does not help.

 

NB: I've set the affected component based on the packages of the stacktrace, but am not sure. Feel free to change it if necessary.
