[jboss-jira] [JBoss JIRA] Closed: (JBAS-5310) Add UNICAST to TCP-based stacks with a thread pool

Add UNICAST to TCP-based stacks with a thread pool -------------------------------------------------- Key: JBAS-5310 URL: http://jira.jboss.com/jira/browse/JBAS-5310 Project: JBoss Application Server Issue Type: Task Security Level: Public(Everyone can see) Components: Clustering Reporter: Brian Stansberry Assigned To: Brian Stansberry Priority: Critical Fix For: JBossAS-5.0.0.CR1 TCP (as in TCP/IP, not the JGroups protocol) ensures the messages from a given sender are received in order. Pre-concurrent stack releases of JGroups counted on this to ensure ordered delivery of messages to Channel.receive(). This worked fine because a single thread carried messages from the transport to receive(). But with a concurrent stack, there is a pool of threads taking messages from the transport and delivering them to receive(). This introduces the possibility of out-of-order messages at receive(). Need to add UNICAST to the TCP-based stacks to impose ordering.
