[jboss-jira] [JBoss JIRA] (AS7-1255) Investigate making HASingleton failover "stopOldMaster" RPC synchronous

Investigate making HASingleton failover "stopOldMaster" RPC synchronous ----------------------------------------------------------------------- Key: AS7-1255 URL: https://issues.jboss.org/browse/AS7-1255 Project: Application Server 7 Issue Type: Feature Request Components: Clustering Reporter: Brian Stansberry Fix For: Open To Community When a node becomes master, it tells any previous master to stop. That call is async, probably because long ago this was done on a JGroups up thread and making a sync call from that up thread would hang. This is no longer done on an up thread, so investigate adding a config option to allow is call to go synchronous, thus ensuring the old master is fully stopped before new one starts.
