In case abbreviation service is requested, NamedConverter will convert fully
qualified class names to their abbreviated from. NamedConverter instances
will store abbreviated names in an internal LRU cache.
The cache will double in size if he cache miss rate is consistently above
30%. Assuming a high miss rate, the doubling until a maximum size of 2048 is
attained. If at this point the cache miss rate is still too high,
NamedConverter will revert to non cached behavior.
The general assumption here is that a large majority of logger names are
concentrated within a group of approximately 1000 logger names.
