             Summary: Subclasses of AbstractWriteKeyCommand don't marshal the Params params field
                 Key: ISPN-6542
                 URL: https://issues.jboss.org/browse/ISPN-6542

          Issue Type: Bug
          Components: Core
    Affects Versions: 8.2.1.Final
            Reporter: Krzysztof Sobolewski


I'm attempting to use the Functional API, but I'm unable to because of an exception like this:

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.
