Just calling this out for other's awareness, but this will only load the
Grok pattern from the classpath. The GrokParser seems to work much harder
looking for a pattern.
Maybe that is what we want in this case, since changing the Grok pattern
might not play well with the rest of the Java code involved with Kyle's parser.
