Darryl Miles commented on WFLY-6663:
------------------------------------

https://github.com/wildfly/wildfly/blob/master/ejb3/src/main/java/org/jboss/as/ejb3/component/stateful/StatefulSessionComponent.java#L242

The line I presume with the NPE.  Was #start() called, is the NPE from this.cache==null ?

> 1 in 8 deployments fail to deploy, usually a redeploy fixes it.
> If there is anyway to get a module state logging out of it, I can send over two logs to compare, one that deploy ok and one that fails.  I guess there is a race bug there somewhere.
