> New versions of JGroups are backwards-compatible to previous versions.
> Solution:
> - Maintain a hashmap of version numbers (keys) with Marshallers (values), e.g.
> 2.2.7: Marshaller-2.2.7
> 2.2.8: Marshaller-2.2.8
> 2.2.9: Marshaller-2.2.9
> We send with each msg a version ID (this is done already). The version ID is the lookup key for unmarshalling a message, so we fetch the right Marsaller
