Batch optimistic updating

Concurrent threads can access the same write method, reading a same entity, modifying it and then writing back the detached entity in the database.In my original code I was reading the latest version of the entity and then copying the field values from the external entity to the latest one.This means the returning records will be locked until commit (or rollback).In this way concurrent updates against London will wait for this transaction to complete.In this way I guaranteed the unbreakable writing code but I felt in the most basic mistake of JPA: I broken the consistency of the entities.From the Mike book: The worse side effect of this trap is that Client A believes the current data persisted in the database is the ones from version 2, but actually it is wrong since the version 3 is currently stored in the database.
