Recovery manager not initialised when deploying just the Coordinator
--------------------------------------------------------------------

                 Key: JBTM-800
                 URL: https://jira.jboss.org/browse/JBTM-800
             Project: JBoss Transaction Manager
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: XTS
    Affects Versions: 4.13.0
            Reporter: Mauro Molinari


If you deploy just the Coordinator component of XTS and you follow the configuration guidelines, you may be providing just the following recovery manager configuration entries in xts-properties.xml:

<entry key="org.jboss.jbossts.xts.recovery.coordinatorRecoveryModule1">org.jboss.jbossts.xts.recovery.coordinator.at.ATCoordinatorRecoveryModule</entry>
<entry key="org.jboss.jbossts.xts.recovery.coordinatorRecoveryModule2">org.jboss.jbossts.xts.recovery.coordinator.at.SubordinateATCoordinatorRecoveryModule</entry>

However, in this way, after the Coordinator has started, you get the following NullPointerException:

Exception in thread "Periodic Recovery" java.lang.NullPointerException
 at org.jboss.jbossts.xts.recovery.coordinator.at.ATCoordinatorRecoveryModule.processTransactionsStatus(ATCoordinatorRecoveryModule.java:280)
 at org.jboss.jbossts.xts.recovery.coordinator.at.ATCoordinatorRecoveryModule.periodicWorkSecondPass(ATCoordinatorRecoveryModule.java:121)
 at com.arjuna.ats.internal.arjuna.recovery.PeriodicRecovery.doWorkInternal(PeriodicRecovery.java:789)
 at com.arjuna.ats.internal.arjuna.recovery.PeriodicRecovery.run(PeriodicRecovery.java:371)

This is because the recovery manager is currently initialized by the ATParticipantRecoveryModule, which is expected to be made available just on the Participant component.
