WARNING: An illegal reflective access operation has occurred

Issue:

Using ragtime, it seems to work for postgres, but I am getting this error:

WARNING: An illegal reflective access operation has occurred

OK, so I did find an answer here https://www.postgresql.org/message-id/CADK3HH%2Byydz_i0%3D5A_706kNawmiGDZoK55ZhNyttyb%3DoqapYYQ%40mail.gmail.com

My source of the version was outdated. org.postgresql/postgresql {:mvn/version "42.1.3"} should be org.postgresql/postgresql {:mvn/version "42.2.12") per: https://jdbc.postgresql.org/

Okay, so nothing to do with Ragtime then?

Correct, thanks.
