Ben O'Day updated AMQ-5942:
---------------------------
    Description: 
the current default factory is the CachedMessageGroupMapFactory and uses an LRU 
with a maxSize of 1024 keys by default.  

Any reason the SimpleMessageGroupMapFactory can't be the default instead since 
it doesn't have a size limit and I'd think perform better for the common use 
cases?
