-----------------------------------------------------------------
Ok, so i looked at JavaBinCodec.ObjectResolver in TransactionLog, it seems to
be easy to put serialization Code there, but the reading side is using
JavaBinCodec to get the objects out of the TransactionLog where a type tag is
required.
Another possibility would be to put it into LogCodec which is extending
JavaBinCodec. The change would be visible to the TransactionLog only. It is not
a perfect solution because LogCodec is depending on JavaBinCodec, but
JavaBinCodec does not know anything of LogCodec by design.
