After upgrading to Flink 1.17, I am running into this exception:

java.lang.ArrayIndexOutOfBoundsException: Index -2147483648 out of bounds for length 5

This is a simple job (one Kafka input, one Kafka output, stateless) with watermark alignment disabled. Is this a bug?

My initial thinking is that could be a bug, related to the introduction of https://issues.apache.org/jira/browse/FLINK-28853

I will, thank you for the prompt reply.
