A serialVersionUID field is defined where it is not expected.
Serialization allows one to dump an object into a file and recover (deserialize) it later. For this to work, Java requires the class of the object to implement the java.io.Serializable interface. Moreover, all instance non-transient fields of the class must be serializable themselves. For inner non-static classes, also the outer class must be serializable. In order to distinguish dumps of objects for distinct versions of the same class, it is required that serializable classes define a static field containing the serial version of the class.

Guarantee that all instance non-transient fields of a serializable class are themselves serializable. Make inner serializable classes have a serializable outer class, or make them static. Add a long serialVersionUID field to serializable classes.
