Stuck thread after session expiry

            ICEfaces 1.6.2 / 1.7-Beta 1, WebLogic Server 9.2 / JBoss AS 4.0.3.SP1

            Description

            I tested both WebLogic Server 9.2.MP2 and JBoss AS 4.0.3.SP1 using both Safari and Firefox. After the session is expired the ThreadBlockingAdaptingServlet nicely gets its shutdown() method invoked, however its service(...) method gets invoked right after which kicks off another blockUntilRespond() cycle. Within this method the semaphore.acquire() method is invoked twice. The second invocation of this method never get unblocked though, resulting in the stuck thread issue.

            I was only able to reproduce this using the head branch, not using 1.6.2.

                QA cannot reproduce it on 1.6 branch subversion 18986.

                Test steps:
                1- build component showcase; replace jsf jars with myfaces jars
                2- deploy the modified showcase war file to webLogic 10.3
                3- load Showcase on FF 3; interact with Progress bar a bit and leave the page untouched till session is timeout
                4- check the server log. No Stuck Thread error is found.

                I think something (Tomcat,icefaces,JVM) is still leaking somewhere. This is because during load testing JVM's CMS Old Gen is commited to the max and GC is unable free any memory. Best JDK so fas has been the latest JDK 1.7.0 snapshot, it manages to free some memory where others (JDK 1.6) stay totally stuck.

                This needs to be backported to the 1.6 branch (1.6.3).

                The blocking connection is unblocked after a period of inactivity, while previously it was unblocked only when the session expired.
                This period of inactivity can be configured with
                'com.icesoft.faces.blockingConnectionTimeout' context parameter. Its default
                value is 30000 (milliseconds). In general this value should be larger than the
                heartbeat interval to avoid unnecessary traffic (unblocking and blocking without
                any updates available).
