> The line where the exception occurs is:
> Param<PersistenceMode> persistMode = command.getParams().get(PersistenceMode.ID);
> Turns out that command.getParams() returns null. Investigating further, it looks like the "params" field of ReadWriteKeyCommand is not marshaled; the receiver then unmarshals everythng except the "params" field, which remains null on the remote node, where the command fails.
