-------------------------------------

[~jamezp] Can yo give me an estimate for this? I have a bunch of other WF Core fixes and wonder if it's worth waiting for this.

>          Components: Logging
>    Affects Versions: 2.0.10.Final
>         Environment: OSX El Capitan, Oracle JDK 1.8.0_92 && 101, swarm 2016.8.1, WF 10.0.0.Final, WF-CORE 2.0.10.Final

> When booting the server from a directory where the subtree is large the server hangs for a long time. JStack shows that the logging subsystem is scanning the CWD.
> Booting the server from the root dir of a maven parent project containing 2 subprojects, a swarm project and a small NPM subproject added 33s to the server boot time compared to stepping into the swarm project and booting it.
> Stacktrace while the server is booting:
