Memory-wise speaking, it is possible to reduce the pressure when (un)marshalling the ReplicableCommand by doing it directly in the ObjectInput/ObjectOutput.

Improvements:

• remove Object array created by get/setParameters()
• remove byte array creating in the externalizer.

Public API change:

• ReplicableCommand interface: deprecate get/setParameters() and create readFrom()/writeTo() methods.
• Marshaller interface: added new start... methods.
