Moulali Shikalwadi updated WFCORE-4901:
---------------------------------------
Workaround Description:
Manually set the TCCL before invoking the method.
{quote}
private void invoke() {
ClassLoader previous = null;
try {
previous = Thread.currentThread().getContextClassLoader();
Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader());
Context ctx = getInitialContext("localhost", 8080, ...);
// look up and invoke remote ejb that uses WildflyInitialContextFactory
} finally {
// reset the TCCL
Thread.currentThread().setContextClassLoader(previous);
}

> TCCL not set to application classloader when MBean Notification is invoked
> If an application registers an MBean notification and it receives a notification, the Thread Context ClassLoader is not set to the application, this causes ClassNotFound exceptions on classes that are in the application's classpath.
