Michael Musgrove commented on JBTM-2180:
----------------------------------------
Initially we should profile which collections are suitable candidates to be replaced. My guess is that _transactions ConcurrentHashMap in TransactionImple could benefit from such a change.

> We use many of the inbuilt collections implementations (such as Hashtable) which are well known to be suboptimal in certain cases. Should be use a separate collections framework, e.g., https://github.com/goldmansachs/gs-collections
> There are pros and cons of doing this. But first we need to determine whether it really makes sense from a performance perspective.
