             Summary: NPE when add ejb3/cache
                 Key: WFLY-1450
                 URL: https://issues.jboss.org/browse/WFLY-1450
             Project: WildFly
          Issue Type: Bug
          Components: EJB
            Reporter: 金沢 栄治
            Assignee: jaikiran pai
            Priority: Minor


In EAP 6.1.0, NPE happens when I add ejb3/cache using the following cli:

  ./subsystem=ejb3/cache=my-cache:add(passivation-store=infinispan)

with the next outputs.
 
ERROR [org.jboss.as.controller.management-operation] (management-handler-thread - 1) JBAS014612: Operation ("add") failed - address: ([

    ("subsystem" => "ejb3"),

    ("cache" => "my-cache")

]): java.lang.NullPointerException

When I add the aliases attribute, it becomes OK, but aliases attribute is nillable, it should ok without the aliases attribute.

And it's OK in EAP 6.0.1 withoutthe aliases attribute.

So I did some research, and it turned out the StringListAttributeDefinition#unwrap will return null when the attribute is not defined.

I also believe there are more subsystems have the same problem other than the ejb3/cache.
