[Dheeraj Joshi (Jira)]

     [ https://issues.redhat.com/browse/WFLY-13391?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dheeraj Joshi updated WFLY-13391:
---------------------------------
    Description: 
We are using managed-thread-factory and Threads belong to this do not have context class loader associated with it

{code:java}
<managed-thread-factories>
    <managed-thread-factory name="FlowWorkManagerThreadFactory" jndi-name="java:jboss/ee/concurrency/factory/FlowWorkManagerThreadFactory" context-service="default"/>
</managed-thread-factories>
<managed-executor-services>
    <managed-executor-service
        name="InteractiveWorkflowWorkManagerExecutorService"
        jndi-name="java:jboss/ee/concurrency/executor/FLOW_MANAGEDEXECUTOR"
        core-threads="${threadpool.interactiveWorkflow.minthread}"
        max-threads="${threadpool.interactiveWorkflow.maxthread}" keepalive-time="5000"
        queue-length="${threadpool.interactiveWorkflow.queuesize}"
        thread-factory="FlowWorkManagerThreadFactory"
        hung-task-threshold="600000" />
</managed-executor-services>
{code}

classLoader variable in below code

{code:java}
final ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
{code}

evaluates as null when called inside managed thread.

Same code works fine with {{Wildfly 16}} and {{Wildfly 17.0.1}}

In 16 and 17.0.1 The class loader is from Service module loader.

Server logs with {{org.jboss.as.ee}}  in {{TRACE}} level for {{Wildfly 16, 17.0.1 and 18}} are attached.
