I found the solution for this. I remove fro my pom.xml files Dynamic-Import and use dynamic-import command in karaf instances on bundle: [ Apache Karaf :: Cellar :: Hazelcast ]
Then ClassNotFoundException disappears and now objects are passing between nodes. I am using: Apache Karaf version 4.1.4 Apache Karaf Cellar version 4.1.1 -- Sent from: http://karaf.922171.n3.nabble.com/Karaf-User-f930749.html
