[Dan Wilkin (JIRA)]

    [ https://issues.jboss.org/browse/AS7-5510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12716650#comment-12716650 ] 

Dan Wilkin commented on AS7-5510:
---------------------------------

A sample invocation would look as follows (nothing unusual or broken here):

{code:title=Green.java}
@Stateless
@Remote(Green.class)
public class GreenSLSB implements Green {
   @EJB
   private Red red;

   public void startup() {
      red.doWork();    <-- exception starts here
   }
}
{code}

> This can occur from a copy-paste error:
> {code:title=RedSLSB.java}
> @Stateless
> @Remote(Red.class)
> public class RedSLSB implements Red {
>    public void doWork() {...}
> ...
> }
> {code}
> {code:title=BlueSLSB.java}
> @Stateless
> @Remote(Red.class)
> public class BlueSLSB implements Blue {
> ...
> }
> {code}
> An invocation on an {{@EJB}} injected _RedSLSB_ on the method {{doWork()}} from within _another SLSB_ (not BlueSLSB) provokes the exception above.  Revising the {{@Remote}} annotation in the example code for _BlueSLSB_ to {{@Remote(Blue.class)}} eliminates this issue.  BlueSLSB turns out to be an arbitrary poorly defined bean uninvolved in the thread of execution leading to the exception.
