Last I looked it was a small handful of classes. Not a big deal. I think 
Jesper used it in ironjacamar. The security subsytem directly linked 
against it. That' something I have been meaning to open a JIRA on, since 
this is technically not a public API it's likely better to copy.

We could have things directly link to the impl, but the above concerns 
apply. We can't directly use Infinispan though because even in local 
mode it adds too much time to boot.

Yeah there is also a real LRU impl too.
