--------------------------------------
[~clerum] FYI, with the Arjuna fix from WFLY-11858, I can get {{Start Batch with Send
using Async CDI Event}} working with following output:
{code}
09:29:17,738 INFO [class com.outjected.demo.MyTestBatchlet] (Batch Thread - 8) Running
inside a batchlet and will send to: test(a)test.local with type: ASYNC
09:29:17,739 INFO [class com.outjected.demo.DemoAsyncEventObserver] (Weld Thread Pool --
5) Starting DemoAsyncEventObserver with sendTo of test(a)test.local
09:29:17,740 INFO [class com.outjected.demo.DemoTask] (Weld Thread Pool -- 5) Sent to
test(a)test.local
{code}
The {{Start Batch with Send using Managed Exectuor}} is still giving the same error
(WFLYWELD0039: Singleton not set...).
Since you are using {{CDI.current()}} there and that is caller sensitive, WildFly does its
best to identify which archive does the call belong to based on {{ClassLoader}}.
There is a class named
[{{ModuleGroupSingletonProvider}}|https://github.com/wildfly/wildfly/blob/master/weld/subsystem/src/main/java/org/jboss/as/weld/services/ModuleGroupSingletonProvider.java]
that holds known references to CLs which have some Weld container running and can, based
on CL, return the container instance. With this test, there is only the following
(expected) entry in the map:
{code}
ModuleClassLoader for Module "deployment.demo.war" from Service Module Loader
{code}
And while queried from within the Batch task, following CL is used:
{code}
ModuleClassLoader for Module "org.jboss.as.ee" version 16.0.0.Final from local
module loader @534df152 (finder: local module finder @52e677af (roots:
/home/manovotn/GitRepo/wildfly/dist/target/wildfly-16.0.0.Final/modules,/home/manovotn/GitRepo/wildfly/dist/target/wildfly-16.0.0.Final/modules/system/layers/base))
{code}
Note that the first sample with Async events only works because there is no
{{CDI.current()}} used in there. Adding it will blow it all the same with the only
difference being that TCCL is {{null}} as [Weld deliberately provides an executor with
erased TCCL to prevent
Managed Executor Task Fails with CDI if created from Batchlet

Key: WFLY-11906
URL:
https://issues.jboss.org/browse/WFLY-11906
Project: WildFly
Issue Type: Bug
Components: Batch, CDI / Weld, Concurrency Utilities
Affects Versions: 16.0.0.Final
Environment: Java 8
Reporter: Cody Lerum
Assignee: Cheng Fang
Priority: Major
This previously was working (verified in reproducer) on Wildfly 14.0.1
Inside of a batchlet if a Managed Executor Task is executed and that Task uses
CDI.current() an exception is thrown
{code:java}
11:00:02,343 ERROR [stderr] (EE-ManagedExecutorService-default-Thread-1)
java.lang.IllegalStateException: WFLYWELD0039: Singleton not set for ModuleClassLoader for

V:\opt\wildfly-16.0.0.Final\modules,V:\opt\wildfly-16.0.0.Final\modules\system\layers\base)).
This means that you are trying to access a weld deployment with a Thread Context
ClassLoader that is not associated with the deployment.
