Well I do not manage multiple access. This is standalone application so trying
to run it twice leads to multiple access, but in such situation JDBC driver
forbids to connect for second instance.
But I will look at it closer. Maybe preventing running two apps silmutanously
would solve all the problems.

IDE disk (C:) on one machine.

They are not supposed to do, but I check what if running the app multiple times.
