[jboss-jira] [JBoss JIRA] (JBAS-9486) Custom thread pools prevent proper shutdown on CTRL-C

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JBAS-9486?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12697380#comment-12697380 ] 

Bela Ban commented on JBAS-9486:
--------------------------------

This also leads to all sorts of issues with JDG:
#1 Shutdown is delayed by ~ 20 secs (TimeSchedulerAdapter is the main culprit)
#2 Restart of nodes leads to the cluster not forming

Removing the 3 thread pools in <transport .../> solves the problem.

> When we define custom thread pool (see in standalone-ha.xml) and use them in (1) the JGroups transport and (2) the AJP connector, CTRL-C hangs. The hang is caused by a shutdown hook waiting on threads which will never terminate (see attached stack trace in dump.log).
