Similar to bug EJBTHREE-862. However, setting `Isolated' to false in $JBOSS_HOME/server/XXX/deploy/ear-deployer.xml does not resolve the issue for me.

Here is the scenario:

There are two applications, app1.ear and app2.ear.

app1.ear contains a stateless session bean, App1Bean, with local and remote interface

app2.ear contains a stateless session bean, App2Bean, which has a field defined like so:

@EJB(mappedName="app1/App1Bean/local") // I've tried local and remote
com.app1.ejb.session.App1 app1;

app1.ear and app2.ear are loaded successfully by the application server.

When App2Bean is activated, JBoss tries to perform the injections. At this point, the RuntimeException (see stack below) occurs.

App2Bean can successfully obtain a reference to app1 bean using the traditional JNDI lookup methods. This is a workaround.

When inspecting the stack, notice the presence of IllegalArgumentException, even though the interface matches.
