I had a vertx application, I migrated to quarkus. To not reimplement everything from scratch I reuse my vertx verticles in quarkus, and these verticles uses vertx-jdbc to access a database. It looks good so far and everythink seams to work except that I see a lot of warnings in the logs which makes reading logs impossible.

Versions I use:

quarkus: 2.16.12 (cannot migrate to 3.x yet cause I use kogito)
vertx: 4.3.7

The lines which are being logged over and over again are:

2024-05-21 21:34:03,598 WARN  [com.mch.v2.c3p.imp.NewPooledConnection] (vert.x-worker-thread-1) [c3p0] A PooledConnection that has already signalled a Connection error is still in use!

I wonder what causes these logs and if it is possible to mute them so it is not flooding my logs. By the way: it is correct that my Gupta SQLBase JDBC driver throws an SQLException(“unsupported method”) for the method being called.

Thank you and best regards,
