You can't just add this in the OR ~/{[^}]{0,50}}/ because that'll not correctly
process escaped } within the brackets.

Will take a look @tballison , thanks for your help. I've been cleaning up
the code to match the checkstyle (which I've only learnt about today) and
testing my janky regexes (in the current form) against some documents I have.
Like I said I managed to build Tika Server and check the config was working
correctly so been a successful few hours today :) Will take a look at your
example tomorrow and hopefully at some point this week find some time to check
the stop method on the other pull request. We can then look to create a
guide/script on how to install Tika Server as a windows service using Daemon.
