Scylla JMX proxy
When a node is part of a cluster but is down (like in the situation where a cluster is taken down and up again but not all nodes are up). There is no application_state information for that node. This patch check that the information exists before using it to prevent null pointer exception. After this patch, a call to nodetool gossipinfo would return the available information without failing.
