@smcvb
I thought It would be good idea to upgrade jgroups dependecy.
There are some changes in jgroups api. For example Message is now abstract so I replaced it with ObjectMessage

First and foremost, thanks for taking the time to make a pull request, @rsobies.
I, however, have somewhat sad news perhaps.

We are at this point in time not sure whether we should proceed the JGroups support.
We have been gathering insights into the downloads of our extensions over the years, and JGroups its part in that has been steadily declining.
Although the final decision has not been made yet, there is thus a real change that we'll archive the extension in the future.

@smcvb
That's fine, I understand
I can say that jgroups has vast ragne of discovery protocols amonung there is one based on database, which I found vary usefull(independet from kube and other enviroments). So far it supports only sql db, but I am preparing pull request that will add suport for mongo. Maybe this will increase interest in this library at least a little bit
