    • The ServerConversationContext.flush() method created in some cases PersistentContext and BusinessContext instances and these instances lived in memory until the HTTP Session was invalidated. This problem is solved by creating them only when required.

      Platform JIRA for JBSEAM-4819.
      The following two objects are leaked, when conversationTimeout occurs.

      org.jboss.seam.bpm.businessProcess
      org.jboss.seam.persistence.persistenceContexts

      This is not a permanent leak, because if associated HTTP session is invalidated, the above objects are removed.
      The object size of the leaked objects are very small,
      so this is not a serious memory leak issue.

      This can be easily reproduced with the seam numberguess application.
