    SBP-2360 | Encapsulated regex pattern matching operation into a separate thread. That
way, in the case of catastrophic backtracking, we can interrupt the thread if it does not
terminate in a reasonable amount of time.

commit 1080b76a739bf620759d5881443ead18ef28f548
Author: Robert Douglas <rdouglas@w2ogroup.com>

    SBP-2360 | Changed to using a ForkJoinPool instead of manually running Threads. Added
test to ensure that regular expressions that cause catastrophic backtracking are timed out
