[jboss-jira] [JBoss JIRA] (WFLY-8705) Watermark policy does not distribute work (distributed workmanager)

Watermark policy does not distribute work (distributed workmanager) ------------------------------------------------------------------- Key: WFLY-8705 URL: https://issues.jboss.org/browse/WFLY-8705 Project: WildFly Issue Type: Bug Components: JCA Reporter: Stefano Maestri Assignee: Stefano Maestri Priority: Blocker Labels: KK-DR18 Reproducing test in https://github.com/LittleJohnII/wildfly/tree/eap7-495 {noformat} # build WFLY first cd testsuite/integration/basic mvn clean test -Dtest='Dwm*TestCase' -Djboss.server.config.file.name=standalone-ha.xml -DtrimStackTrace=false -Darquillian.launch=distributed-group {noformat} The watermark test will fail and logs will show that work wasn't distributed to the second node when the amount of threads available got down to 1 (and watermark = 1). Even with the default watermark setting, the work is never distributed - if thread pool size = 2 and 3 instances of work are executed, the third always waits for the previous two to finish on the first node. [~maeste] is already aware of the issue - it was discussed on HipChat prior to the Jira creation, so this is mainly a tracker. I'm setting blocker priority since I'd like to have watermark working before EAP7-495 is resolved (I think this is the most important policy setting, and the default too). If this is a problem, we can discuss lowering the priority and pushing EAP7-495 out anyway, since this isn't a thing that breaks the whole DWM.
