From comment : #17259 (comment). During the JDK 17 upgrade(#17168), IntelliJ inspections have identified 30 instances of serialVersionUID fields that should be annotated with @serial. This annotation was introduced in JDK 14 (JEP 359) and finalized in JDK 17. Since this is a JDK 17-specific feature, we'll address this as part of our post-migration cleanup.

Add the @serial annotation to all flagged fields:

`+ import java.io.Serial;

public class Example {

• @serial
  private static final long serialVersionUID = 1L;
  }`
