[weld-issues] [JBoss JIRA] Issue Comment Edited: (WELD-833) ConcurrentModificationException while deactivating conversations

ConcurrentModificationException while deactivating conversations ---------------------------------------------------------------- Key: WELD-833 URL: https://issues.jboss.org/browse/WELD-833 Project: Weld Issue Type: Bug Components: Conversations Affects Versions: 1.1.0.CR3, 1.1.0.Final, TBC Reporter: Jan Groth Assignee: Ales Justin Fix For: 1.2.0.Beta1 Attachments: fix_deletion_of_conversations.patch If a conversation gets deactivated, the code which actually iterates the map of conversations in org.jboss.weld.context.AbstractConversationContext is erroneous and easily runs into a ConcurrentModificationException if there is more than one conversation. We consider this a pretty serious defect because its not possible to use JBoss AS 6.0 GA for a real-world application. See attached patch for a fix.
