    Description

      I've noticed several tests that run O.K. with Oracle JDK7 and fail with Oracle JDK8. One can reproduce these failures anytime, they are not just random glitches.

      Notes on the setup:

      • simplecontext-666 is a simple JSP web app, non-distributable
      • clusterbench is a distributable webapp
      • all the tests use 1 worker node and 1 balancer
      • many clients throwing many requests at the simplecontext-666 context

      Stop Context Timeout test

      First, there is the setup with stop-context-timeout="20":

      <subsystem xmlns="urn:jboss:domain:modcluster:1.2">
     <mod-cluster-config advertise-socket="modcluster" stop-context-timeout="20" connector="ajp">
         <dynamic-load-provider>
             <load-metric type="busyness"/>
         </dynamic-load-provider>
     </mod-cluster-config>
 </subsystem>

      On JDK7, one may observe exactly the desired behavior. On a clean shutdown, message Failed to drain 294 remaining pending requests from default-host:/simplecontext-666 within 20.0 seconds is displayed. See the whole log here: 1-server.log.

      On the other hand, with JDK8, this utterly fails. No waiting for pending requests, no message. See the whole log here: 2-server.log.

      These are the Apache HTTP Server logs, showing exactly what was the test doing:
      Note that thousands of "GET /simplecontext-666/ HTTP/1.1" messages were omitted from these snippets.

      In the aforementioned snippets, it is noteworthy that the JDK8 run sent only one STOP-APP message. This is confirmed in error logs:

      JDK7, error_log, grep STOP-APP (See the complete log here 1-error_log.zip)

      [06:47:20] mod_manager.c(1901): manager_trans STOP-APP (/)

[06:47:40] mod_manager.c(2666): manager_handler STOP-APP  OK

      JDK8, error_log, grep STOP-APP (See the complete log here 2-error_log.zip)

      [06:43:25] mod_manager.c(1901): manager_trans STOP-APP (/)

[06:43:25] mod_manager.c(2666): manager_handler STOP-APP  OK

      One could argue that there was a test error and the JDK8 test run actually didn't access simplecontext-666 application. Let me dissolve this argument right away:

      grep -c "GET /simplecontext-666/ HTTP/1.1\" 200" ./targetJDK8/httpd/logs/access_log 
27250
grep -c "GET /simplecontext-666/ HTTP/1.1\" 200" ./targetJDK7/httpd/logs/access_log 
27927

      Default settings, the same problem...

      Trial with the default settings reveals the same problem with some additional findings in the Apache's error log.

      <subsystem xmlns="urn:jboss:domain:modcluster:1.2">
    <mod-cluster-config advertise-socket="modcluster" connector="ajp">
        <dynamic-load-provider>
            <load-metric type="busyness"/>
        </dynamic-load-provider>
    </mod-cluster-config>
</subsystem>

      On JDK7, one may observe exactly the desired behavior, this time with the default 10 seconds timeout. See the whole log here: 3-server.log.

      In the access logs, it is noteworthy that both clusterbench and simplecontext-666 sent ENABLE-APP, but there was only one STOP-APP message. Furthermore, who and why used OPTIONS method?

      Default settings, again

      I had considered the JBAS010151: Unable to get transaction state: java.lang.IllegalStateException being probably an unrelated glitch, so I tried the default test run with JDK8 again. Test failed, yet this time without any exception. Nothing has changed since the last run as far as environment and configuration are concerned.

      JDK8 fails. No waiting for pending requests on /simplecontext-666. See the whole log here: 5-server.log.

[07:45:41] "OPTIONS * HTTP/1.0" 200 - "-" "Apache/2.2.26 (Red Hat Enterprise Web Server) (internal dummy connection)"

      This time, there were two STOP-APP messages all right, but instead one of them being for clusterbench and the other one for simplecontext-666, they were both for clusterbench. I find this behavior being a rather disturbing one.

      JDK8, error_log, grep STOP-APP (See the complete log here 5-error_log.zip)

      [07:45:40] mod_manager.c(1901): manager_trans STOP-APP (/)
[07:45:40] mod_manager.c(2617): manager_handler STOP-APP (/) processing: "JVMRoute=jboss-eap-6.3&Alias=default-host%2Clocalhost%2Cexample.com&Context=%2Fclusterbench"
[07:45:40] mod_manager.c(1429): process_appl_cmd: STOP-APP nbrequests 0
[07:45:40] mod_manager.c(2666): manager_handler STOP-APP  OK
[07:45:40] mod_manager.c(1901): manager_trans STOP-APP (/)
[07:45:40] mod_manager.c(2617): manager_handler STOP-APP (/) processing: "JVMRoute=jboss-eap-6.3&Alias=default-host%2Clocalhost%2Cexample.com&Context=%2Fclusterbench"
[07:45:40] mod_manager.c(1429): process_appl_cmd: STOP-APP nbrequests 0
[07:45:40] mod_manager.c(2666): manager_handler STOP-APP  OK

      Again, there were plenty of requests sent to simplecontext-666/:

      grep -c  "GET /simplecontext-666/ HTTP/1.1\" 200" ./targetJDK8/httpd/logs/access_log

      WDYT?

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
