----------------------------------------------------
Nothing much to review here *smile*
Looks good, +1.
bq. On another note, do we really need to use ResourceBundles for the counter
names, or is this something we can do away with?
Great question. Not even sure if anybody uses this at all. I guess we should
just file a ticket and see if someone responds.
Pushing this in.
