I checked FarmWarDeployer's code. When WAR is updated, FarmWarDeployer sends UndeployMessage and sends FileMessage after that. The node which received UndeployMessage undeploys war. The node which received FileMessage deploys war.
If FileMessage is received while processing UndeployMessage, the following error messages will be outputted. "SEVERE: Application /example in used. touch war file example.war again!" In the case of asynchronous replication (default), FileMessage may be received while processing UndeployMessage. I think that it may be better to process updated war by one message. Although I consider correction of a code, there is one work around. Workaround is change in synchronous mode.
