The Java 11 -> 17 upgrade requirement for the operator must be discussed on the Flink Mailing list before this is merged

[gyfora]

should this be InformerEventSourceConfiguration.from(FlinkSessionJob.class, FlinkDeployment.class) ?

[csviri]

fixed, good catch, thank you!

[gyfora]

I wonder how this worked in our e2es or if we are missing some key test coverage :D

[csviri]

Actually not, it is just used for the default secondayr to primary mapper. So actually the API might be on JOSDK side. So this is not a mandatory field.

Overall looks good, I had a minor comment/question
