Tim Ellison updated HARMONY-2752:
---------------------------------


Just reproducing the ICU team comment here for convenience.  They closed it as won't fix.

"This works as designed. Some of the rules can get really large and complicated. If you want a collator that works with less memory, don't use the rules and open a collator based on the locale."
