      It was discovered that the <methodname>ServerConversationContext.flush()</methodname> method created unnecessary PersistentContext and BusinessContext instances which remained in memory until the HTTP Session was invalidated. In some cases this caused a minor memory leak. The memory leak issue is now fixed by adding a condition to the method which creates PersistentContext and BusinessContext instances only when needed. This functionality fixes the memory leak issue.

      Backport of JBPAPP-6751.

      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.
