Can't connect to Oracle 19.3 with 19.3 JDBC driver

We have a project running with an Oracle 19.3 database, and a Java application using the Oracle 19.3 JDBC driver (which is available on Maven Central). On Windows with JRE 1.8, everything is fine, but when I run either on our build server or in WSL Ubuntu with OpenJDK 11.0.3 it refuses to connect to the database. Specifically: 

ERROR: Unexpected error
java.sql.SQLRecoverableException:

If I switch in the 18.3 JDBC driver everything is fine in both environments; if I switch in an 18.3 database everything is fine in both environments. That does give us a workaround for now, but it feels very uncomfortable that we don't understand what's going on. And I can't find anything online about an "Authentication lapse". Can anyone see any clues which would explain the failure?

It looks like the underlying Socket implementation is not allowing OOB. As a workaround, you can disable the OOB check by setting the connection property CONNECTION_PROPERTY_THIN_NET_DISABLE_OUT_OF_BAND_BREAK to "true". Please refer this link : https://docs.oracle.com/en/database/oracle/oracle-database/20/jajdb/oracle/jdbc/OracleConnection.html#CONNECTION_PROPERTY_THIN_NET_DISABLE_OUT_OF_BAND_BREAK

The link above no longer mentions the "out of band break" issue, so here's some alternatives:

I had the same issue with an Oracle 19c docker container, and after browsing half of the internet, I realized that the problem came from the fact that I used localhost as the Host, which for some reason is not supported by the 19.3.0.0+ Oracle driver.

After configuring the host with the IP address of the docker network interface (172.17.0.2 in my case), I could connect to Oracle server.

Hope this can help you as well.
