> OIFactory has various caches and most of them are accessed by key containing OIs. But
OIs are not forced to implement hashCode/equals and that is resulted to some kind of memory
leakage. 
> Considering the price of calculating/accessing hashmap, just removing those caches are
better solution, IMHO.
