Project: WildFly
Issue Type: Bug

Reporter: Aaron Ogburn
Priority: Minor
Fix For: 8.0.0.CR1
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:

The core pool size needs to be adjusted in line with the max pool size and in the right
order to avoid that since max threads can't be less than core threads.
