[jboss-jira] [JBoss JIRA] Created: (JBAS-5923) Weak hash map usage in UnifiedInvokerHAProxy is not thread safe

Weak hash map usage in UnifiedInvokerHAProxy is not thread safe --------------------------------------------------------------- Key: JBAS-5923 URL: https://jira.jboss.org/jira/browse/JBAS-5923 Project: JBoss Application Server Issue Type: Bug Security Level: Public (Everyone can see) Components: Clustering, Transaction Manager (JBossTM) Affects Versions: JBossAS-4.2.3.GA, JBossAS-5.0.0.CR1 Reporter: Galder Zamarreno Assignee: Galder Zamarreno txFailoverAuthorizations weak hashmap that is now also used for maintaining transaction stickyness was created as an unsynchronized WeakHashMap and this was causing issues. It was not enough to synchronise on the tpc (key of map) whenever we manipulated it because two threads, trying to store different tpcs could end up trying to resize the map and as a result, key value pairs could easily dissapear from the hash map. This is extremely confusing because we thought the disappearance was due to garbage collection. instead. Thanks to Adrian for the help debugging this. -- 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
