XML transformer does not support indentation: java.lang

Hi guys,
I'm getting the above error in my RapidMiner Server log 7.1
(http-/127.0.0.1:8080-2) XML transformer does not support indentation: java.lang.IllegalArgumentException: Not supported: indent-number
It repeats several times. Any idea what might be the cause? Server itself doesn't seem to be too bothered by it when running.
My working theory is that it's because I installed a MariaDB repository with the MySQL connector. Going to upgrade to PostgreSQL (which I admit, I should have done to begin with) but wondering if you think the problem is this or something else?
Best,
JEdward.

Hi,
no need to worry about it. It's about some XML transformer not supporting setting a specific indent number. I don't know why this is logged. Can be safely ignored anyway
