             Summary: Implement graceful shutdown for transactions
                 Key: WFLY-4937
                 URL: https://issues.jboss.org/browse/WFLY-4937
             Project: WildFly
          Issue Type: Feature Request
          Components: Transactions
    Affects Versions: 10.0.0.Alpha5
            Reporter: Michael Musgrove
            Assignee: Michael Musgrove
             Fix For: 10.0.0.Alpha6


We will handle suspend for JTA and JTS by disallowing new transactions and then block the suspend thread until the count of active transactions drops to zero. We will also suspend the recovery manager.

We will *not* do graceful shutdown for the optional XTS subsystem. For example an incoming XTS request for an existing transaction will be blocked. 

Question: should we
- raise a new JIRA for this XTS case;
- document the deficiency and see if there are complaints;
- document the deficiency and fix it in a subsequent release
