Flink compatibility with JDK17

[amenreet sodhi <am...@gmail.com>]

Hi,

I wanted to confirm if Apache Flink is compatible with JDK17. If not, when
can we expect this to happen? What major issues will I face if I try to
compile it with JDK17?

Thanks
Regards

Hi Amenreet Singh Sodhi,

Flink is compatible with JDK8 and JDK11, not with JDK17. You can find the
Jira issue that tracks compatibility at
https://issues.apache.org/jira/browse/FLINK-15736. The biggest problem is
the Kryo serializer that's currently being used. That doesn't work with
JDK17, but upgrading would break compatibility so is not trivial.

Best regards,

Martijn
