Do you mind to specify which PGX version, where you got it from and what is the OS you are using?
pgx-3.2.0 and it is a Oracle Linux 7.
I actually fixed this. I was running the client and not the server. When I did run the server, the problem does not show up.
Good to hear all is good.
And I can confirm 3.2.0 works fine on OL7.
Both the server and the java-client to connect to a running server.
