Entity with Jackson Builder throws exception when updated with Repository through HTTP PATCH

[Laures]

An Entity that uses a builder to be deserialized with Jackson will cause an exception during PATCH requests. The builder-based deserializer does not support updates. I'm not sure there is a way to resolve this, but it would be nice if this is mentioned in the data-rest documentation.

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Deserialization of [simple type, class media.tiger.account.account.Account] by passing existing instance (of media.tiger.account.account.Account) not supported at [Source: UNKNOWN; byte offset: #UNKNOWN]

Please provide a Minimimal Reproducable Example, preferable as a Github repository. Make sure to include the database, either as an in memory database or if that is not possible using Testcontainers.

Here is an example with an H2 database. We use Lombok so i created one example with and one without Lombok on the entity
