------------------------------------------
Summary: Flink 1.18.1 and 1.19.0 having build jdk 1.8 and causing
incompatibilities with Java 17
Key: FLINK-35470
URL: https://issues.apache.org/jira/browse/FLINK-35470
Project: Flink
Issue Type: Bug
Components: Flink CDC
Affects Versions: 1.18.1
Reporter: Rajat Pratap Singh
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?
