Hello,
The nested enum java.time.temporal.JulianFields.Field declare a
serialVersionUID field. Per the serialization spec, a serialVersionUID
field in an enum is ignored.
"The process by which enum constants are serialized cannot be
customized: any class-specific writeObject, readObject,
readObjectNoData, writeReplace, and readResolve methods defined by enum
types are ignored during serialization and deserialization. Similarly,
any serialPersistentFields or serialVersionUID field declarations are
also ignored--all enum types have a fixed serialVersionUID of 0L.
Documenting serializable fields and data for enum types is unnecessary,
since there is no variation in the type of data sent."
https://docs.oracle.com/javase/10/docs/specs/serialization/serial-arch.html#serialization-of-enum-constants
Therefore, this misleading field should be deleted; please review the
patch below which does this.
Thanks,
-Joe
