[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3999) Race condition in component initialization

Race condition in component initialization ------------------------------------------ Key: JBSEAM-3999 URL: https://jira.jboss.org/jira/browse/JBSEAM-3999 Project: Seam Issue Type: Bug Components: Core Affects Versions: 2.1.1.GA Reporter: Stuart Douglas When starting up application (or session) scoped component that do not have an @Startup annotation it is possible to get a race condition where two instances of the component are instantiated, as no locking is present in component initialization. I ran into this when my multi-threaded reporting process was the first component to hit the cache and jboss cache provider got instantiated twice: `16:54:48,717 INFO [JbossCacheProvider] Starting JBoss Treecache 1.x 16:54:48,717 INFO [JbossCacheProvider] Starting JBoss Treecache 1.x` In this case it is easy to work around, by simply adding startup="true" to the application scoped component. It is also possible to make calls on a component before the create method is called. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
