This problem occurs when injects a local ejb in interceptor class :

Code:

public class testInterceptor {

private static final Logger log = Logger.getLogger("TEST_INTERCEPTOR");

@EJB(name="ejb/testSessionLocal", beanInterface=testSessionLocal.class)
private testSessionLocal test;

@AroundInvoke()
public Object showMessage(InvocationContext ctx) throws Exception {

log.debug("Persist entity from testSessionBeanLocal...");

for (Object o :ctx.getParameters()){

log.debug("Interceptor parameter : "+ o);
if (o instanceof String)

}
Object o = null;
o=ctx.proceed();
return o;

}

the method intercepted by this class is as follows:
Code:

@Remote(testSessionRemote.class)
@Stateless(name="testSessionRemote", mappedName="testSessionBeanRemote")
public class testSessionBeanRemote implements testSessionRemote {

private static final Logger log = Logger.getLogger("TEST_INTERCEPTOR");

@Interceptors(testInterceptor.class)
public void persist(String cmdParam)

}
