> Project: Flink
> Issue Type: Bug
> Components: Flink CDC
> Affects Versions: 1.18.1
> Reporter: Rajat Pratap Singh
> Priority: Critical
>
> I am writing flink jobs with latest release version for flink (1.18.1). The
> jobmanager is also deployed with the same version build. But we faced issues
> when we deployed the jobs. On further investigation, I noticed all libraries
> from flink have build jdk 1.8. is this the correct version? How to write
> flink jobs with Java 17 code and which library versions to use? Is Java 17
> even supported on the client side or is it just on the server side support
> for java 17?
