> Currently PojoCache supports transaction rollback. For instance,
> cache.attach(id, pojo);
> is transactional even if there is no user transaction. However, with user transaction,
> tx.begin();
> cache.attach(id, pojo);
> pojo.setAge(20);
> tx.rollback();
> the replication is rollbacked but the in-memory copy is not, e.g., pojo.getAge() == 20. There is a workaround if you are using transaction by yourself:
> // Just make sure this one succeeds first.
> tx.begin();
> cache.attach(id, pojo);
> tx.commit();
> // All subsquent field update will be transactional then.
> tx.begin();
> pojo.setAge(20);
> tx.rollback();
