As suggested in [https://discuss.elastic.co/t/logstash-jdbc-class-cannot-found/209807](https://discuss.elastic.co/t/logstash-jdbc-class-cannot-found/209807) I changed the driver library to

> jdbc\_driver\_library =\> "c:/logstash/logstash-7.5.0/lib/jars/mariadb-java-client-2.4.2.jar"

but my jdbc connection via logstash 7.5 still don't work. Are we looking at a **undokumented breaking feature**?
