------------------------------------------------------------------
[~clebertsuconic], JNDI would be appealing for anybody who doesn't want to put
implementation classes in their code.
I'm not sure what you mean by, "...things get messed up as you would have only
the last one affecting the setting." Can you clarify this point?

> Artemis clients use by default an unbounded global thread pool

> Key: ARTEMIS-312
> URL: https://issues.apache.org/jira/browse/ARTEMIS-312
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Broker
> Affects Versions: 1.1.0
> Reporter: Jeff Mesnil
> Assignee: Justin Bertram
>
> While investigating some performance issues, we noticed that Artemis clients
> (including MDBs) use by default a "global" pool by creating a cached thread
> pool with 0 core pool size, Integer.MAX_VALUE max size and 60s keep alive.
> This default global pool looks misconfigured. If a Artemis clients has a lot
> of activity it is actually possible that threads are deleted from the pool
> and added back.
> Related to this, Artemis defines a threadPoolMaxSize attribute if the client
> is not using a global pool. But the property does not seem to be well name.
> If the Artemis client is using a "non-global" pool, this property is used to
> create a newFixedThreadPool. So this property defines the actual size of the
> pool, not a max size.
> As a comparison, the "global" scheduled thread is instantiating with a 5 core
> pool size.
