    Description

      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).
