[jbossts-issues] [JBoss JIRA] (JBTM-2180) Determine whether or not we should use a specific collections framework

Mark Little commented on JBTM-2180:
-----------------------------------

So I suggest stepping back from testing the collections within Narayana initially. It'd be good to look at what we use and determine what we *could* use as replacements. Then write some standalone tests that compare and contrast how these various collections perform independently. Once we have that data we should get together and review. Therefore, we're not looking at testing all of these collections implementations against each other, only a subset of what we think we need.

> We use many of the inbuilt collections implementations (such as Hashtable) which are well known to be suboptimal in certain cases. Should we 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.
