> There is a problem in the way Derby handles LOBs (see
> db-derby-10.4.2.0-bin/docs/html/ref/crefjavbclobnot.html). The
> getClob/getBlob method can only be called once which generates an error at
> serialization time because we fetch first the object using getObject and we
> try to serialize it later using getxxxStream on the Lob which breaks with
> Derby.
> Therefore we need a BackendObjectConverter that converts Lobs to native types
> on-the-fly so that serialization does not break.
