Agroal - DB connection pool Dev UI empty for MSSQL #50014
Description
Describe the bug
The Agroal - DB connection pool in the Dev UI is empty when using MSSQL.
(obviously the db does work, however it just never shows in this view)
Expected behavior
If I switch to PostgreSQL it does show it immediately in the Agroal - DB connection pool in the Dev UI
Actual behavior
No response
How to Reproduce?
Create a fresh Quarkus App with Rest, Hibernate and the MSSQL JDBC Driver
Start the app and open the Dev UI and navigate to the Agroal - DB connection pool
You will also see the following stack trace in the console:

Additional information
I think this has never really worked for MSSQL (and I failed to create a bug report earlier for it)
