[SUPPORT] Unable tu run Netbeans on MAC OS 12.01

[Giovanni De Martino]

Hi all,
I’ve just installed NetBeans 12.5 on my Mac Book Air M1 with Mac OS Monterey 
but, when I launch it, I just see the splash screen and then NetBeans stop to 
run.

If I run it from the Terminal, this is what I see:

If I run Netbeans as root (sudo…), it works.

Please can you help me to figure out what is blocking the normal execution?
Which is the file NetBeans is trying to open/write for which it does not have 
proper access rights?
May I enable a more verbose log at startup so I have more information to debug?

Thanks in advance,
Giovanni
