It may contain instances of classes that disappeared > from runtime classpath (e.g. if implementation of CacheStore has been > renamed). In such case, node will fail on start. > We should handle this and show meaningful message with instruction how to > overcome this issue - delete cache_data.dat and restart cache. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
