> Because ParseUtil manages it's own parser threads by creating a thread for every parse
it sometimes happens that specific parsers are very expensive. For example, parsers that have
threadlocal fields will initialize them for every item to be parsed.
> By simply introducing a caching ExecutorService the ParseUtil will be able to cache threads
therefore parsing more efficient. See attached patch.
