> According to the documentations, when doing a REST PUT, "Any existing data will be replaced", but when the cache is configured to store "application/x-java-object" (unserialized objects) and the object does not implement the equals method, the replace always fails and the server returns HTTP 412 (precondition failed).
> This is due to the fact that internally the REST server first retrieves the existing value, and then does a conditional replace with this value that never matches.
