             Summary: Decreasing max-threads on a unbounded queuesless executor generates IllegalArgumentException
                 Key: WFLY-2336
                 URL: https://issues.jboss.org/browse/WFLY-2336
             Project: WildFly
          Issue Type: Bug
    Affects Versions: 8.0.0.Beta1
            Reporter: Aaron Ogburn
            Priority: Minor


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
}

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