Issue/Introduction

In a Master / Subordinate architecture, the UVMS Subordinate does not display correctly the status of the Master UVMS, even though the traffic is opened and the status of the Master is correctly displayed in the Master UVMS.

When increasing the Main log Level to "DEBUG" on the UVMS Subordinate, the following NullPointerException appears:

| 2021-09-01 07:53:15 |DEBUG| Master Synchronize process | com.orsyp.central.synchro.MasterSynchroPoolFeeder | Excepion in PooldThread java.lang.NullPointerException at com.orsyp.central.synchro.MasterSynchroPoolFeeder.checkStatusForMaster(MasterSynchroPoolFeeder.java:249) at com.orsyp.central.synchro.MasterSynchroPoolFeeder.runTasks(MasterSynchroPoolFeeder.java:170) at com.orsyp.central.synchro.MasterSynchroPoolFeeder.run(MasterSynchroPoolFeeder.java:142)
