Symptoms
Few times I got "The trustAnchors parameter must be non-empty" alert after Java Admin Console login and whole "Security Management" section was unavailable
Diagnosis
In Java Admin console log it looked like:
[6/15/21 10:57:43 PM MSK {1623787063262}] [262144] SecureTransport-> Setting SNI to web server to load client compatible certificate:[NBCA]

(SR-1)readFile: (Sent:Wed Jun 16 01:13:58 MSK 2021, Recv:Wed Jun 16 01:13:58 MSK 2021)
Protocol Code: 4
Status: 2
Time Taken: 96ms
Error Msg: No such file or directory
In this case it happened because of localized name of the user and the folder with certificates became unavailable or it can be just a permission issue
Solution
Create another user (it's also possible to re-configure and use another folder) or fix issues with the folder
