------------------------------------

This looks similar to an issue we discussed with a user on #jboss IRC recently. Here's what he found out http://sourceforge.net/mailarchive/forum.php?thread_name=AANLkTinzx_uLiLP-mwG9I7Tx80OS1oTX2wxtGfLMKvrp%40mail.gmail.com&forum_name=resteasy-developers

> I'm making use of the recent EJB3.1 support in JBoss6M2 to deploy a stateless session bean within a war. This bean also implements a JAX-RS annotated interface and is called as a web service. 
> The session bean uses dependency injection to get a JPA EntityManager and the EJB SessionContext:
>     @Resource 
>     private SessionContext context;
> 	 
>     @PersistenceContext(unitName="drs2_services")
>     private EntityManager em;
> The problem is that calling my service sometimes fails with a NullPointerException where I make use of the EntityManager or the SessionContext. This behavior is inconsistent and sometimes works. 
> To add more detail: 
> If I call the service and I get a NullPointerException on the EntityManager, I can work around the issue by restarting the service until the call succeeds. After it succeeds once, I won't see the NullPointerException again (until, perhaps, I restart the JBoss again).
> The SessionContext issue is a little trickier. I am able to call my webservice from the browser successfully, but when using Java's HttpUrlConnection class, I consistently get a NullPointerException on the SessionContext. 
> I followed the RestEasy 1.2 guide for configuring and annotating my project, specifically chapter 38 "EJB Integration." I didn't bundle the ReastEasy jars in my war since they are bundled with JBoss 6. 
> Any help is appreciated, I'm happy to provide more details/code if desired.
