-----------------------------------------
The first PR caused a problem on Windows 10 where this stack-trace is logged and the broker fails to start:

> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 2.10.1

> The changes from ARTEMIS-2441 caused a regression of the issue fixed by ARTEMIS-1417.
> The changes in ARTEMIS-1417 made sure to lock/unlock the {{server.lock}} file when reading the state information in order to deal with stale data over NFS.
> However, the changes from ARTEMIS-2441 split the lock into several different files which means that when the state information is read now the {{server.lock}} file itself is not locked/unlocked which results in reading stale data on the slave.
