Because my application works with very large collections of integers, Eclipse Collections seems like a very useful framework because of its primitive collections. I've tested it already, happy to see significant performance and memory improvements - so much that I'm considering just ditching the JDK Collections altogether (even for parts of my application where the improvements wouldn't be noticeable at all) - mostly for the sake of being consistent and using only one collections framework.
But that may sound too good to be true - perhaps I am missing a key disadvantage in regards to ditching JDK's Collections for Eclipse's.
The only one thing that occurs to me is that whatever future update/feature Java may have in regards to collections, I may not be able to make use of it until Eclipse adapts to it.
Is there any reason I might not want to transition completely to Eclipse Collections?
