[mod_cluster-issues] [JBoss JIRA] (MODCLUSTER-399) Draining pending requests fails with Oracle JDK8

Michal Babacek created MODCLUSTER-399: ----------------------------------------- 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.
