Support for Hazelcast client-server topology - SessionUpdateEntryProcessor not public

[cdene]

Hello everyone!

I have Hazelcast client/server topology
I saw that issue #1101
But unfortunately, I can't implement that code in where i create my Hazelcast client:

clientConfig.getUserCodeDeploymentConfig().setEnabled(true) 
 			.addClass(Session.class).addClass(MapSession.class) 
 			.addClass(SessionUpdateEntryProcessor.class); 

Because SessionUpdateEntryProcessor is package private
Is that default access modifier correct?

Also, i have an issue with adding MapSession.class through UserCodeDeployment

Thank you

Thanks for the report @cdene! This indeed is an omission, as you obviously cannot use SessionUpdateEntryProcessor in your app's Hazelcast configuration unless it's public.

Regarding the second part of the question, it appears you haven't enabled user code deployment in your Hazelcast server config. See the config we use in our integration tests as an example.
