[jboss-jira] [JBoss JIRA] (WFLY-2336) Decreasing max-threads on a unbounded queuesless executor generates IllegalArgumentException

[Aaron Ogburn (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-2336?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Aaron Ogburn updated WFLY-2336:
-------------------------------

    Description: 
Create an unbounded queueless executor

<unbounded-queue-thread-pool name="uq-thread-pool">
<max-threads count="350"/>
<keepalive-time time="5" unit="minutes"/>
</unbounded-queue-thread-pool>

Modifying max-threads fails:

/subsystem=threads/unbounded-queue-thread-pool=uq-thread-pool:write-attribute(name=max-threads,value=300)
{
    "outcome" => "failed",
    "failure-description" => "JBAS014749: Operation handler failed: null",
    "rolled-back" => true
}

ERROR [org.jboss.as.controller.management-operation] (management-handler-thread - 1) JBAS014612: Operation ("write-attribute") failed - address: ([
    ("subsystem" => "threads"),
    ("unbounded-queue-thread-pool" => "uq-thread-pool")
]): java.lang.IllegalArgumentException
	at java.util.concurrent.ThreadPoolExecutor.setMaximumPoolSize(ThreadPoolExecutor.java:1620) [rt.jar:1.7.0]
	at org.jboss.threads.JBossThreadPoolExecutor.setMaxThreads(JBossThreadPoolExecutor.java:95) [jboss-threads-2.1.1.Final.jar:2.1.1.Final]

	at org.jboss.as.threads.UnboundedQueueThreadPoolService.setMaxThreads(UnboundedQueueThreadPoolService.java:91)


The core pool size needs to be adjusted in line with the max pool size to avoid that.
