Nagios test with jmeter plugin failed with CRITICAL: ... java.util.prefs.FileSystemPreferences$1 run

Question

The issue have been reproduced for a fresh installed and upgraded Lubuntu 20.04 with 5.4.0-42-generic kernel, Nagios 4.4.6, Java 1.8.0_265, Jmeter 5.3.

When run this plugin manually:

user@ubuntu:~$ /usr/bin/perl /usr/local/nagios/libexec/jmeter.pl -j=/usr/local/nagios/share/jmeter -p=/usr/local/nagios/libexec/test.jmx -t 80 -w 90 -c 100
OK :  | sum_time=26.91
user@ubuntu:~$ echo $#
0

Once I've got the same result as on the screenshot above by running the same using sudo, but could not reproduce it again:

$ sudo /usr/bin/perl /usr/local/nagios/libexec/jmeter.pl -j=/usr/local/nagios/share/jmeter -p=/usr/local/nagios/libexec/test.jmx -t 80 -w 90 -c 100

Googling for

WARNING: Could not lock User prefs.  Unix error code 2

Which I got by reviewing debug log file (sudo tail -F /usr/local/nagios/var/nagios.debug) I've found out I have been required to create /home/nagios folder:

$ sudo mkdir /home/nagios
$ sudo chmod nagios:nagios /home/nagios

After this the next folders have been created in case of nagios service processing:

root@ubuntu:/home/nagios/.java# ls -ailh
total 0
100900054 drwxr-xr-x 4 nagios nagios 44 сер 19 23:23 .

   109430 drwx------ 3 nagios nagios 73 сер 19 23:23 .userPrefs

And nagios started displaying OK status:
