(Adding back user mailing list) Hi Anissa, Thank you for coming back with the results. I hope this might be helpful for someone else in the future and maybe it will be one more argument for the Flink community to address this issue in some other way.

I took a little time to look for all the possibilities to use FlinkML in Java, but that's not possible as you told me. After looking in other libraries in Java, I chose the MOA library in combination with flink API for anomaly detection streaming which gives quite satisfactory results.
