Summary: Draining pending requests fails with Oracle JDK8
Key: MODCLUSTER-399
URL:
https://issues.jboss.org/browse/MODCLUSTER-399
Project: mod_cluster
Issue Type: Bug
Affects Versions: 1.2.8.Final
Environment: RHEL7 x86_64, Apache/2.2.26 (Red Hat Enterprise Web Server), Oracle
JDK 8
Reporter: Michal Babacek
Assignee: Radoslav Husar
Draining pending requests fails with Oracle JDK8
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
h3. Stop Context Timeout test
First, there is the setup with {{stop-context-timeout="20"}}:
{code}
<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>
{code}
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].

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])

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

h3. Default settings, the same problem...
Trial with the default settings reveals the same problem with some additional findings in
the Apache's error log.

h3. 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

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])

Again, there were plenty of requests sent to {{simplecontext-666/}}:
{noformat}
grep -c "GET /simplecontext-666/ HTTP/1.1\" 200"
./targetJDK8/httpd/logs/access_log

WDYT?
