[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1233) Regression in ClusterIdGenerator

[Galder Zamarreño (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1233?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12614211#comment-12614211 ] 

Galder Zamarreño commented on ISPN-1233:
----------------------------------------

The problem is that by the time ClusterIdGenerator is created in AbstractProtocolServer.start(), the cache manager has already been started and a view has been defined. So, ClusterIdGenerator is waiting for a view change to set the base version but this does not happen since there's no view change after that. A solution could be to initialize ClusterIdGenerator with the current view if the cache manager is already started and a view is available (i.e. at least one of its caches has been started)
