Additional info
* Ontop 4.2.1 CLI
* Windows 10 Pro
* using jdbc driver for Dremio
Scenario
I wanted to perform a to-r2rml conversion, so I started the following command
c:\prog\ontop-cli\ontop.bat mapping to-r2rml -i jml.obda -p jml.properties
Problem
The CLI outputs the following:

- I tried in identical fashion on Ubuntu 20.04LTS and the command works fine.
- Windows accesses the Dremio through an SSH tunnel on localhost, while Ubuntu can access it directly. I do the same for the Ontop Protégé plugin on Windows and that seems to work fine with the same properties file.

The Java version might be relevant.
On Windows:
openjdk 17.0.2 2022-01-18 LTS
OpenJDK Runtime Environment Corretto-17.0.2.8.1 (build 17.0.2+8-LTS)
OpenJDK 64-Bit Server VM Corretto-17.0.2.8.1 (build 17.0.2+8-LTS, mixed mode, sharing)
OpenJDK Runtime Environment Corretto-17.0.2.8.1 (build 17.0.2+8-LTS)
OpenJDK 64-Bit Server VM Corretto-17.0.2.8.1 (build 17.0.2+8-LTS, mixed mode, sharing)
On Ubuntu:
openjdk version "1.8.0_342"
OpenJDK Runtime Environment (build 1.8.0_342-8u342-b07-0ubuntu1~20.04-b07)
OpenJDK 64-Bit Server VM (build 25.342-b07, mixed mode)
OpenJDK Runtime Environment (build 1.8.0_342-8u342-b07-0ubuntu1~20.04-b07)
OpenJDK 64-Bit Server VM (build 25.342-b07, mixed mode)
I didn't try other versions on Windows yet, so if you think it might be related, let me know and I'll try another version that should work according to your background knowledge.

Hi Johan,
The Dremio JDBC driver used to have issues with Java 11 (https://community.dremio.com/t/java-11-jdbc-support/5443/17?page=2).
Can you please give a try to a more recent version?
Best,
Benjamin

Thanks for your suggestion.
The newest version that I found is version 22.1.1, but trying that leads to exactly the same issue.
A fragment:

But since you refer to some issues experienced with Dremio + newer Java versions in the past, I tried Java 11 anyway and that seems to solve the issue.

Therefore, I guess that this is not a Ontop issue, but a Dremio one.
And - as you expected - Dremio is aware of it:
Stupid on my end not to have checked that first. Thanks for you pointing me to it.
Best regards,
Johan
