In macOS Big Sur some NetBeans panels (settings and find in project) are broken:
- they are shown in full screen, as tab, please see screenshot
- when they are shown, NB completely hangs, with high CPU usage.
I tried almost every version of NetBeans (from 8.2 to 12.2rc) with every JDK (1.8, 11, 13, 15), with the same behavior.
The only way I have to solve the issue is to run NB as sudo
Of course this is a permission related issue, but it appears only on NetBeans. Other Java apps seems not affected. On command line there are no evidence of the crash.
Finally, in our office we are 4 with the same MacBook, and same macOS (just upgraded from Catalina to Big Sur). 2 out of 4 have this issue. The other 2 can run NB without the sudo command.
