[jboss-jira] [JBoss JIRA] (WFLY-11906) Managed Executor Task Fails with CDI if created from Batchlet

---------------------------------------------------------------

[~cfang] FYI *something must have changed around thread pool that batch uses* as in WFLY 14 calling {{Thread.currentThread().getContextClassLoader()}} returns {{ModuleClassLoader for Module "deployment.demo.war" from Service Module Loader}} while in 16 this is different (see my comment above).
That explains why the first option(_Start Batch with Send using Managed Exectuor_) worked in 14 but doesn't in 16.

Nonetheless, this doesn't solve the trouble we have with async events and with the fact that users can even use custom executors.
