[jboss-remoting-issues] [JBoss JIRA] Updated: (JBREM-1107) SocketServerInvoker.IdleTimeoutTask interrupts ServerThreads during long invocation

[Ron Sigal (JIRA)]

     [ https://jira.jboss.org/jira/browse/JBREM-1107?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ron Sigal updated JBREM-1107:
-----------------------------

        Fix Version/s:     (was: 2.5.0.SP3 (Flounder))
    Affects Version/s:     (was: 2.5.0.SP2 (Flounder) )


I'm removing 2.5.0.SP3 from the fix version list because the additional synchronization introduced in version 2.4.0 should prevent this problem.  In particular, SocketServerInvoker$IdleTimeoutTask.run() calls the synchronized method ServerThread.shutdown(), which can't be entered as long as the ServerThread is in the synchronized method ServerThread.completeInvocation(), which is the case once ServerThread reads an invocation and begins to process it.

> org.jboss.remoting.transport.socket.SocketServerInvoker.IdleTimerTask is intended to shut down org.jboss.remoting.transport.socket.ServerThreads that haven't been in use for some configured amount of time.  For each ServerThread, it compares the value of System.currentTimeMillis() to the time at which the ServerThread last started or finished processing an invocation, and, if the difference exceeds the value of the "idleTimeout" parameter, it shuts down the ServerThread.
> The problem is that if processing an invocation takes longer than the value of "idleTimeout", a ServerThread could be shut down DURING the processing of an invocation.
