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

             Summary: Nullpointer exception on AbstractSessionBeanStore.getLockStore from within Activiti CDI
                 Key: WFLY-3386
                 URL: https://issues.jboss.org/browse/WFLY-3386
             Project: WildFly
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: CDI / Weld
    Affects Versions: 8.0.0.Final
         Environment: CentOS, Mac (Mountain Lion).
            Reporter: Andries Ehlers
            Assignee: Stuart Douglas


Background:
The actual exception seems to be very close the one in issue: WFLY-3001 but we are not using JSF at all, but Activiti CDI.

Not sure if this is a Wildfly or Activiti issue - it could very well be that there is a bug in Activiti with how it manages the CDI scopes.  Unfortunately we're at a loss and seeing that the nullpointer is thrown from within a weld AbstractSessionBeanStore, I decided to post it here.  Please advise.

Error:
We use Activiti CDI within Wildfly 8.0.0.Final.  We randomly encounter an issue (sometimes immediately after a redeploy, other times after a few hours of inactivity on the server) the following issue.  When Activiti attempts to retrieve the ContextBeanInstance from its ConversationScopedAssociationProxy, a NullPointer exception is thrown while attempting to retrieve the lock store within Weld (see below).
