Non-serializable field in a 'Serializable' class
Reports non-serializable fields in classes that implement java.io.Serializable. Such fields will result in runtime exceptions if the object is serialized.
Fields declared transient or static are not reported, nor are fields of classes that have a writeObject method defined.
This inspection assumes fields of the types java.util.Collection and java.util.Map to be Serializable, unless the types they are declared in are non-Serializable.
Example:
Locating this inspection

NonSerializableFieldInSerializableClass- Via Settings dialog
Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.
Use the following options to configure the inspection:

Serializablefrom a superclass but are not intended for serialization.List annotations that will make the inspection ignore the annotated fields.
Whether to ignore fields initialized with an anonymous class.
