DB error on 4.15.0 running on W10 64bit

Hello all,
while using autopsy for analyzing some disk image files, I earned the following error:

(Unable to close connection to case database, caused by SQLException…).
I have got more than 20.000 error messages like that.

Now, my question is: was the analisys fine? Do I have to run it again, with, for example, a different java virtual machine?

Thank you for your answers.
