This bug is not urgent, I think.

At the same time, another notification I got was:

A java.io.FileNotFoundException exception has occurred. However, the system should continue working without further problems. Click Show Details for the stack trace.

Maybe this was caused by some plugin imported from version 12.0 to 14.

After further testing, the first notification appears everytime I try to open a XHTML file, and NetBeans won't open that XHTML file.

Same error in Apache NetBeans 17 and OpenJDK 17.0.7+7-LTS. NetBeans won't open any file.

I found this error after my pc ran out of battery and the drive where I had NetBeans got disconnected. Seems like the cache got corrupted, because deleting NetBeans' cache and restarting it fixed the problem
