Probe doesn't works after update oracle lib

[Bruno Barros]

After updating our lib from ojdbc6.jar to ojdbc8.jar the probe stopped working. Now when trying to access it the error below appears:

Has anyone seen this happen?

Tomcat: 9.0.35
JDK: 11.0.23
Probe: v4.3.1

[Bruno Barros]

We found out what happened: on the recommendation of information security, we changed the Tomcat settings to hide its version, by editing the "Application Server" property. Without this information the probe stops working. How can I configure the probe to work without this information?
