> In case of using Zookeeper Discovery, cluster node which joins to a cluster receives information that some user-classes have been already deployed but doesn't exist in the local classpath. In this case, the node tries to request for these classes from nodes that contain it, but do it synchronously during Zookeeper Discovery starting and gets NullPointer when first topology snapshot has not initialized yet.
> We should request for user-classes asynchronously and only after the first topology has initialized.
