errael opened a new issue, #4652:
URL: https://github.com/apache/netbeans/issues/4652
### Apache NetBeans version
Apache NetBeans 15
### What happened
NetBeans crash after declining to import settings
### How to reproduce
- staring with clean .nb/15 (some -J-D added to netbeans.conf)
- execute script: ./runme which contains something like
bash /ref/nb/NetBeans/NetBeans-15/netbeans/bin/netbeans \
--jdkhome /ref/openjdk/java_home \
--userdir /home/err/.nb/15/userdir \
--cachedir /home/err/.nb/15/cachedir \
&> /junk/Caches/nb/15/LOG &
- no to import
- OBSERVE: startup/netbeans crashes: ~/bugs/nb/startup-stop/log-1
The first exception is from following the instructions above. I also
occasionally see the 2nd exception when starting up netbeans; try again, and
maybe again, and it works.
