What are the built in executors in EAP 6 ?

Issue

• Which are the six build-in Executor classes in EAP 6?
• Which Executor is suitable for the ajp Connector?
• Is there a document that describes the available options for the threads subsystem
• What are the thread pool options in the threads subsystem in JBoss EAP 6?
• Migrated below thread configuration from EAP 6.2 to 6.4. Would like to confirm it will still work in in EAP 6.4 and are there any changes needed in any xml tags for the Thread configuration or require any additional parameter specifics to EAP 6.4 :

<subsystem xmlns="urn:jboss:domain:threads:1.1">
            <bounded-queue-thread-pool name="ajp-executor" allow-core-timeout="true">
                <core-threads count="4096"/>
                <queue-length count="1024"/>
                <max-threads count="4096"/>
                <keepalive-time time="30" unit="seconds"/>
            </bounded-queue-thread-pool>
        </subsystem>
