After restarting a DAS instance, undeploying the connector module fails when cascade is set to false. (ID 6188343)

Description

In this scenario, a standalone or embedded connector module is deployed in DAS and connector connection pools, and resources are created for the deployed module. After restarting the DAS instance, undeploying the connector module fails when cascade is set to false with the following exception:

[#|2004-10-31T19:52:23.049-0800|INFO|sun-appserver-ee8.1|javax.enterprise.system .core|_ThreadID=14;|CORE5023: Error while unloading application [foo]|#]

Solution

Use cascaded undeploy (set the cascade option to true) for undeploying standalone and embedded connectors after restart of the DAS instance.
