[jira] [Created] (FLINK-25956) KryoSerializer is noisy in scala-free Flink

Chesnay Schepler created FLINK-25956:
----------------------------------------

             Summary: KryoSerializer is noisy in scala-free Flink
                 Key: FLINK-25956
                 URL: https://issues.apache.org/jira/browse/FLINK-25956
             Project: Flink
          Issue Type: Technical Debt
          Components: API / Type Serialization System
    Affects Versions: 1.15.0
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler
             Fix For: 1.15.0


When scala is not on the classpath and Kryo is used the {{KryoSerializer}} logs a full ClassNotFoundException as a warning.

Since this is now an expected situation it should logged on info. The exception should only be logged if debug logging is enabled.
