jsduck Thread.exclusive is deprecated, use Mutex

After fresh installation on Ubuntu 16 there's a lot of this messages:

Thread.exclusive is deprecated, use Mutex

Perhaps upgrading parallel gem will simply do the trick.

If these messages are bothering you, you could try doing:

gem install parallel -v 1.10.0

and see how JSDuck behaves after that.

Nope, didn't help:

After installation of parallel 1.10.0 "jsduck" was using the same old 0.7.1 version. After uninstallation of parallel 0.7.1:

Docs updated

Any advice? This message definitely bothers me, as they completely floods the build logs. I've kind of "solved" the problem with:

#!/bin/bash

DIR="$( cd "$( dirname "$0" )" && pwd )"

$DIR/jsduck_original "$@" >/dev/null 2>&1

but then I miss output about possible real errors.

I could try creating a release with upgraded dependency on parallel, but that will take a while, as I haven't really touched this code-base for years. Don't really take my word for it... I've intended to do some maintenance for years, but the last release was 3 years ago.

Would be great. Pretty sure there will be more and more requests as people will start upgrading to ubuntu 16..
