'@Serial' annotation used on wrong member

Reports methods and fields in the Serializable and Externalizable classes that are not suitable to be annotated with the java.io.Serial annotation.

Examples:

class Test implements Serializable { @Serial // The annotated field is not a part of serialization mechanism because it's not final private static long serialVersionUID = 7874493593505141603L; @Serial // The annotated method is not a part of the serialization mechanism because it's not private void writeObject(ObjectOutputStream out) throws IOException { } }
class Test implements Externalizable { @Serial // The annotated method is not a part of the serialization mechanism as it's inside Externalizable class private void writeObject(ObjectOutputStream out) throws IOException { } }

For information about all valid cases, refer the documentation for java.io.Serial.

This inspection depends on the Java feature '@Serial annotation' which is available since Java 14.

New in 2020.3
