The solution is to use our own Serializer/Deserializer to make class from plugin/bundle can be found.

Steps to reproduce on Master:
1) Start one portal node with cluster enabled by setting "cluster.link.enabled=true" to portal-ext.properties
2) Start another portal node to create a cluster with the first one, you would see error log(master-error.log)

Steps to reproduce on 6.2:
1) Start two portal nodes with cluster enabled by setting "cluster.link.enabled=true" to portal-ext.properties
2) Deploy test-misc-portlet-6.2.10.1.war on two nodes and add it to home page

Before fix, you would see exceptions on console, after fix, you would not see exceptions and all tests listed in test-misc-portlet passed
